  20. 20 : Susy indrayanti Says:


  21. 21 : ruler Says:

    I watching this drama because of 2nd lead actor INFINITE’s L/Myungsoo.INTERESTING PLOT.

  22. 22 : Ashley Says:

    Why people are saying 40 episodes is beyond me, it’s really just 20 episodes in total (2x 30min) with a big commercial break in-between.

  23. 23 : hana_goh Says:

    i like like like it very much! Good act yoo seung ho! aii..

  24. 24 : DeeAn Says:

    I’ve been watching 4th episodes. And It was interesting story. This gonna be great drama this year . ^_^

  25. 25 : MaxT Says:

    This drama has a very interesting plot and first 4 episodes were great.

    Highly recommended. 9/10

  26. 26 : Simon K Says:

    This is one of the few Korean period dramas that do not follow real history and I think it is a good thing, this give the writers more freedom for story plot. After 4 episodes, I think this will be a great drama. As I stated somewhere else, MBC produce great period dramas.

  27. 27 : Vanessa Says:

    The only downfall about this show is I hate that they had to cut the episodes in half for financial reasons. After watching episode 1 I was so confused I was like yelling at my tv saying “what the fck” that was until I figured out that it was cut in half and I had to watch part 2 of episode 1. I remember saying “what the fck is this mess?” I feel like it is beyond irritating to have to be stopped in the middle of the show to play the freaking next part!! (-_______-)

  28. 28 : Lemon Says:

    Love this drama. Sheung Ho is great actor. I can feel his character in this drama. Keep watching him since he small and now become so handsome. Hopefully this drama will be 1-rank. Cant wait for ep 7..

  29. 29 : Joy Says:

    I am soooo loving this…

  30. 30 : Jenna Says:

    Loved this drama

  33. 33 : Vi2n Says:

    Mudah2an aku salah..aku asal nebak mungkin putera mahkota (pengganti) akan merebut tahta putera mahkota yg asli krn mereka menyukai han ga eun. Dalam pembunuhan ibu putra mahkota di dalangi ibu suri.

  34. 34 : yuewe Says:

    30 minutes per 2 episode back to back like My Sassy Girl it means 20 episode only.

  35. 35 : Hannah Says:

    This drama is so good! I can’t seem to predict at all what’s going to happen next!

  36. 36 : Mangali-nepal Says:

    I loved this drama a lot

  37. 37 : lemon Says:

    Yeah hwaiting!! give rating up to 40%

  38. 38 : Kim Says:

    This drama is from 3 dramas: The Moon That Embraces The Sun, Moonlight Drawn by Clouds & Scarlet: Moon Lovers.
    It doesn’t make sense that you could kill the King and there is no issue.
    Actually I always like to watch saeguk drama from MBC such as Dong Yi & The Moon That Embraces The Sun. But, this time I would like to say this is a poor concept 🙁

  39. 39 : tigerb Says:

    a direct time slot competition is ‘two episodes back to back’, same as this one. to me it’s annoying when it can be aired in one stretch.

  40. 40 : Hannah Says:

    I also thought that how is it there are no consequences at all after killing the King? I thought it’s an act of treason. But then again, I remembered that most of the ministers and even the chief magistrate is under Dae Mok. And the chief royal guard was killed, so I assume they change the story of how the King died. Plus, the Crown Prince is the poor Lee Sun and becomes the puppet of Dae Mok, so there’s no one to actually gives order to royal guard or magistrate that Dae Mok had done treason.

  41. 41 : Hannah Says:

    This is one of the few dramas that I actually prefer second heroin than the heroin itself. Hwa Gon has better character and saves Lee Sun a lot of times. I’m more impressed that she could be in the merchant business without her grandfather’s help at all. She hates that Dae Mok tried to kill His Majesty, her love, and she abandoned him and left with Gon.

  42. 42 : Robinof The Forest Says:

    @hannah. At first i like her too, but you should notice, we dont know hwa gon moral limit. She is the one who just because of her curiosity causing lee sun the fake king’s father death by telling the big bodyguard guy to punish water stealer. Anyone would push away who take her precious thing away from her, that is why she leave her grand father…just for awhile..And we ll see she may cause harm to han ga eun because of jealousity. She is different from Han ga eun who has a kind heart. Even though she is not a strong woman, she s fighting her best to protect her people by motivating, support and lead them. The difference is Hwa gon acts base on her romantic feeling, but Han ge eun acts base on what she has to do for the other people best, and she has a great heart.

  43. 43 : sanjinyeon Says:

    While watching this, suddenly I remember another story of Rebel, Yoo Seung Ho is like Yun Kyun Sang their both peddlers in the Joseon era, their both like Robinhood and their both really cute in their long hair. Anyway the story of Rebel and this one are both nice and worth to watch.

  44. 44 : Sarang Says:


  45. 45 : Beautiful Says:

    I just love this drama a lot
    Hope to see a kissing sence between the lead 😘😘

  46. 46 : charlotte Says:

    This drama is so wow can’t wait to watch this. I really love it

  47. 47 : Kyu Says:

    This drama is highly recommended!
    Besides yoo seung ho good acting skill, his chemistry with kim so hyun is so undeniable! Sadly, Seems like MBc didn’t give them much romance scene in this drama:(,I hope next episode MBC will give them much romance scene like others drama , cant wait to looking forward for the next episode, aaah~ and so drooling with their upcoming kissing scene ♡♡

  48. 48 : Hannah Says:

    Ohhh this drama is so good! Good old love rectangle is something that I like. I don’t need kissing scenes or whatever, the storyline itself is already good that I love the tension between all the main casts.

    I think I can say all the main casts (Yoo Seung Ho, Kim So Hyun, Yoon So Hee and L) did a good job. Their acting skills are just superb. I love all four of them! ❤️

  49. 49 : Hannah Says:

    And I still haven’t moved on with my bias towards Hwa Gon. In ep 14, I feel sad for her as she had to choose betwen family and love. As much as I hate that she betrayed Lee Sun, I’m still glad that she chose family over love eventhough her family is the bad one. I could see how hurt she was betraying Lee Sun. She’s just unlucky to be born as Dae Mok’s granddaughter.

  50. 50 : fb Says:

    two lead are goog to each other

  51. 51 : Saranglove Says:

    Totally into this drama
    Awww love these duo..their chemistry are just awwww but how come these two still have no kissing scene 😅😅

  52. 52 : Hero Says:

    I’m such huge fan of this drama.. just can’t imagine what will happen next??but I’m totally hoping for kissing scene of these two like other drama …
    Hehehe fighting

  53. 53 : Momo Says:

    Just three words for this drama wow wow wow
    There is Really touching a scene when I see these two leads..it makes me cry too.. acting are just so superb

  54. 54 : Minu Says:

    I’m shipping for these couples
    Plz plz I want more romantic scene of these two
    Lee sun ❤️Ga eun

  55. 55 : Alexandra Says:

    No chemistry between the leads I don’t understand why Korea insist in putting these 15 yrs. olds in love-lines with older men. Still enjoying the Kim Hwa Goon storyline.

  56. 56 : Lisa Says:

    Kim So Hyun is already 18 this year and Yoo Seung Ho is 23, it’s not really much of age difference. It’s the same age gap between Kim Yoo Jung and Park Bo Gum in MDBC.

  57. 57 : Kyu Says:

    Hello may i ask something? If ga eun being a court lady, could she marry the king (real Lee seon) ?

  58. 58 : Jenna Says:

    Woah I’m in love this drama

  59. 59 : Robin lim Says:

    When is this writer ever going to write more love love chemistry for these two leads..

  60. 60 : Sandy Says:

    I really think this drama going to have a big twist 😭😭😭I can’t bear to see Ga eun with the commoner lee sun

  61. 61 : jessieca Says:

    i really love kim so hyun..i want to watch this drama but i am here in the philippines..

  62. 62 : candy Says:

    I really love them ❤️❤️

  68. 68 : Mangali Says:

    My best drama so far
    And I’m big fan of Kim so hyun

  69. 69 : Hannah Says:

    Too many parties in this drama which kinda messing with my head.

  70. 70 : Lisa Says:

    Actually I don’t like Ga Eun’s character. She’s the stubborn one and always acts without thinking the consequences. I think she’s kinda selfish as she pushed Chun Soo away not only once, but TWICE. I get it she wants to reinstate her father’s honor, but girl, your late dad already said it’s not the Crown Prince’s fault. He only did his duty. Plus, the late Royal Concubine also said that Pyunsoo group was behind her father’s death. At which part of her father’s letter and Lady Hee Bin’s statement that she didn’t understand?! And now she broke Chun Soo’s heart again by joining the queen selection process and got into trouble. Just how many times Chun Soo must saves her when she got into trouble?

    And of course, the real Crown Prince, our Chief Peddler would always be by her side no matter how many times she broke her promise and left him. And of course, Chun Soo would hate Hwa Gon just because she lied to him for being Dae Mok’s granddaughter and a apart of Pyunsoo group no matter how many times she saves him and helps him with his mission.

    Don’t get me wrong, I’m not in team Hwa Gon. I think both of them don’t deserve Crown Prince/Chun Soo, even Chun Soo doesn’t deserve Hwa Gon. Well, I think they all don’t deserve each other. There, I said it.

    (I know I’m being so extra, but please don’t feel butthurt with my comment. peace)

  71. 71 : shiro Says:

    I do agree with the comment of #70
    I like Hwa Gon’s character more than Ga Eun’s.
    Hwa Gon is always next beside the crown prince and always helps him more than Ga Eun has done for the crown prince (well, she had saved the prince who fell from the cliff). But I think Hwa Gon did much more than Ga Eun.

  72. 72 : Minu Says:

    Whatever they say
    I love you Ga Eun
    You have ur reason
    Ofcaz she didn’t left him because she wants too it caz the she wants to clear her dad name

  73. 73 : Nayam Says:

    I love this drama ❤️

  74. 74 : Lisa Says:

    OMG thank you for agreeing!

    As far as I’m concerned, well, I do give credit to Ga Eun for jumping off the cliff to save Crown Prince, but I don’t think she’s the one who pulled both of them out from the sea. I remember that scene and it seems to be that Ga Eun also lost her conciousness while trying to untie Crown Prince. I get the feeling that it’s the mysterious court lady who saved both of them, idk.

  75. 75 : Mangali Says:

    I love you Ga eun
    You have really justified this role ❤️😍

  76. 76 : Henry Says:

    I am with you
    Yes Ga eun is the lady of character

    This drama is make me can’t wait for the next episode. Very wonderful.
    But why the acting of 2nd lead actress better than main lead actress, i thought.

  94. 94 : Jenna Says:

    To Kyo
    Omg seriously are you blind or you have no sense of talent..
    That second lead actress just have one expression on her face..how can you b comparing her to so hyun
    So hyun acting is far far beyond her reach
    No offence huh

  95. 95 : Sandy Says:

    Why this love is painful 😫😭

  96. 96 : Sandy Says:

    omg this drama
    I can feel lot of painful love

  97. 97 : Me Says:

  98. 98 : Sarang Says:

    Now can’t wait for the next episode
    My poor lee sun and ga eun
    When are you guy going to bring that pyunsoo group down
    Can’t wait for them to be destroyed

  99. 99 : Miss thapa Says:

    I really hate the writer for showIng ga eun a weak character where supposed to be a such a strong lady 😫

  100. 100 : Hee hee Says:

    Ya I do agree with you miss
    So hyun is such a strong person
    I hate it when she begin shown a weak person
    Next esp she is getting slap shit
    I hate the writer too
    Plz change the story

  101. 101 : Hannah Says:

    I love Kim So Hyun; I think I watch most of her dramas, but in this drama, I don’t find myself liking Ga Eun’s character. Hwa Gon seems to outshine Ga Eun, to be honest. I feel sad when Hwa Gon confessed her love toward Crown Prince.

  102. 102 : Oppa Says:

    My poor ga eun
    Same here I too feel bad for her character
    I am a huge fan of her since I watch her in I miss you
    Plz writer be good to her

  103. 103 : Happy Says:

    The character I love most rite now is Yoo seung ho
    I feel sad when he crys
    My poor Ga eun I feel really bad for character begin pro cast badly here.
    The second lead actress she could have shown better emotion then the same repeating expression always
    And the fake king thoug he betrayed the real cp
    I still like him.. his acting has been improving a lot

  104. 104 : Hannah Says:

    I knew it I knew it that the royal guard seems suspicious!!!! I knew that he’s with Dae Mok all along. He seemed suspicious from the very beginning when he saved fake King from killing himself, why would he follow the fake King secretly? And how on Earth Dae Mok knew that Lee Sun would meet with his family if not his “most-trusted” royal guard?

    And what’s up with fake Lee Sun being all annoying just because of a girl? I guess bros before hoes do not exist in Joseon era. Huhh

  105. 105 : Wonder Woman Says:

    Can’t wait to kick dae mok ass
    Writer plz show some mercy
    No more crying scene

  106. 106 : Juggy Says:

  111. 111 : Miss You Says:

  119. 119 : silverswan Says:

    One of the best Historical drama this year, though it is short and until Episode 28, it was all the way exciting and with all so good actors and actresses this really a good drama among so many. Looking forward to the last few episodes and hope we do not have to wait too long for the 12 more episodes
    Thank you for making such a great drama , really enjoyed watching

    They are both so talented

    Yoo seung ho oppa and Kim so hyun

  124. 124 : Coolbeans Says:

    Another disappointment that started good and melted in the middle. Can’t blame the acting. Blame the script. The Crown Prince would have died in each episode except the granddaughter of the evil organization saves him. The love triangle is a hot mess with the fake prince turned cokehead and blindly trying to win the girl while hiding his true ID. The girl blindly seeks revenge creating real danger for everyone in the love triangle while continuously acting without thinking of the consequences. Another female lead character presented weak and not too smart. The only likable character is the granddaughter of the evil villain and the evil villain also known as the drug pusher. Both remain true to character and plausible. The others make you tear your hair out and frustrated just about half way through this mess.

  125. 125 : Joy Says:

    Im liking the character hwagun. She’s fighting for her love…. shs is with strong disposition. The other girl? So disappointed with her…. she does not trust the love of the king…. grrr hating her talaga…..kakainis sya and the other lee sun. What kind of love do these 2 people have?

  126. 126 : Sue Says:

    8 episode (20min each) / 2 Week to go.. mean 4 episode to go.
    Cant wait for next week episode… haaaa why in wednesday

  127. 127 : Jeewit Says:

    Excellent acting by all
    I’m saddened by how poorly the character is written for the first lead actress
    No matter what ga eun
    You have our full support

  128. 128 : shiro Says:

    Omooo… I am totally falling in love with Hwa Gun’s character. She loves crown prince sincerely. Her character is not like the other second leads in the other dramas. She deserves crown prince’s love rather than Ga Eun. :'(

  129. 129 : Hannah Says:

    I remember saying that I love Hwa Gon in here and twitter when everyone else replied to me saying, no Ga Eun is so much better and question Hwa Gon’s value of love when she caused the death of Crown Prince’s favorite eunuch. And now most of viewers like Hwa Gon’s character and think she’s awesome. I love that people have changed their focus on Hwa Gon. You gotta admit, she saves Crown Prince most of the time and always help him. What did Ga Eun do? Hmmm

  130. 130 : Era Lestari Says:

    this drama is totally disappointed me 😑😑😑

  131. 131 : Jeewit Says:

    2weeks more to go before it ends😭😭

  132. 132 : sanjinyeon Says:

    I am not easily getting emotional watching kdrama, but this is the 2nd time I cried over a character. My tears can’t stop falling seeing the death of Hwa Gun, I felt heaviness in my heart, the scene is so heart breaking, totally love can change everything it can turn you to be good or evil person, it can hold so much sacrifices that even death cannot swayed you.

  133. 133 : Marykay2507 Says:

    Falling in Love with L KimMyungSoo once again, he improved his acting so much. This dorama helped him a lot. I wished HwaGun and LeeSun(L-KimMyungSoo) have some lines, I love seeing them together since “the day after we broke up”, the had good chemistry there

  134. 134 : Lemon Says:

    4 episode. 1 week to go.. cant wait….

  135. 135 : Cy Says:

    Can’t wait for next week last 4 episodes!
    For me, the fake king deserves to die. He’s so greedy.

  136. 136 : M.U.S.A Says:

    My poor Hwa Gun 🙁

  137. 137 : Jenna Says:

    I totally love this drama
    But I’m disappointed with the writer by how poorly Ga Ga eun character is written..
    So hyun is super talented
    So plz do utalized her talent dude

  138. 138 : Mango Says:

    Can’t wait for the next episode
    It gonna be super fun between the real n fake cp

  139. 139 : Kpop fan Says:

    I’m so proud of these actors
    They gave such a awesome performance
    I’m in love with the lead actress Ga eun
    Her simplistic just blow me away ❤️

  140. 140 : Chef Says:

    I just love Yoo seung ho
    The lead actress n Yoo seung ho
    They are just so perfect for each other
    The shyshy couple
    Can’t wait for the next episode
    Can’t wait to see that dae Mom in doom

  141. 141 : tigerb Says:

    @admin: i don’t know if there’s a disclaimer at the start of each episode that this drama is fiction, but in the list of cast above, the crown prince sado lee sun was not the son of king yeongjo. lee sun was the son of prince sado, whom king yeongjo killed by putting him in a rice chest to die (that’s what i learned in previous dramas i’ve watched and read at wikipedia). as i am curious about other country’s history, and think that watching your dramas can give me some input, it is confusing for me if the drama is not declared fiction loosely based on some historical figures, like in the other s.k. dramas i’ve watched.

  142. 142 : Kimo Says:

    Can’t believe this drama going to end tomorrow

  143. 143 : roberto Says:

    @tigerb: i get what you are saying but it is a DRAMA, what can you expect?. EXPECT that most of the plot of All kind of dramas are FICTITIOUS. if you want to learn about Korean history go to your library or surf the internet with good sources. a drama created to entertain, enjoy, and inspire the viewers and Asian drama fans. Remember, you are watching a DRAMA not a Documentary.

  144. 144 : roberto Says:

    wow! what a great drama. I’m so sad that it will end tonight!. Yoo Seung Ho and Kim So Hyun are great actor and actress.

  145. 145 : Jenna Says:

    It was a happy ending ❤️❤️
    They look so good in that king n queen robe
    Can’t wait to see them together again

  146. 146 : sanjinyeon Says:

    the ending is quite phenomenal seeing the spirit of Master Han,Hwa Gun and Sun, people who gave their lives for the success of the king, but for me it is more appealing if the spirit of Dae Mok show also with a word ” I wish I had a king like you a little sooner” because even he’s a villain he made the king become wiser and stronger with a heart…

  147. 147 : silverswan Says:

    I had finished all the episodes and still think this is the best excellent drama among so many this year and hoping they will earn a reward for it, should be top ranking for Historical drama. All the actors and actresses were excellent , it is thrilling , exciting, romantic and so good that you want to watch again
    Yoo Seung Ho as Crown Prince Sado Lee Sun
    Kim So Hyun as Han Ga Eun
    L as commoner Lee Sun
    Yoon So Hee as Kim Hwa Goon
    Heo Joon Ho as Dae Mok
    Park Chul Min as Woo Bo (Lee Sun’s teacher)
    Best actors and actresses

    Best of the best :
    Production Company: People Story Company, Huayi’s Brothers
    Planner: Kim Kyung Hee
    Producers: Jung Chan Hee, Bae Jung Hoon, Shim Jung Woon
    Directors: Noh Do Chul, Park Won Gook
    Screenwriter: Park Hye Jin, Jung Hae Ri

    Hoping to have such good drama again soon

  148. 148 : Lemon Says:

    Will missing all cast…

  149. 149 : Hyu young Says:

    I cried when L died
    I feel so pity for him atleast I didn’t hate his character
    The ending was just wow
    Such a great acting by all of them
    Esp Yoo seung ho and Kim so hyun

  150. 150 : tigerb Says:

    @ roberto: i understand what you are saying, but like i said, there was no disclaimer that was put at the start of each episode. in other recent s.k. historical dramas i’ve watched, they’d put such disclaimer, at least the producer is being responsible enough. what i am saying is in the cast list above, yoo seung hoo’s role is Crown Sado Lee Sun, which is erroneous. did I not say that i read at wikipedia? that’s one way for me to learn and understand what historical s.k. dramas i’ve watched. if there was a disclaimer, i would not even bother checking as i know for sure that it is fictitious! i’ve watched quite a few dramas, and i’ve learned that each writer and/or producer have their own interpretation, or how they would like the plot/story to appear to their audience. point is lee sun is not crown prince sado, and the late king in this drama is listed as king yeongjo, who in history was the father of prince sado and the grandfather of prince lee sun. i don’t think you’d be interested what i learned, and it is not really important, so i let it be. and yes, if i want to learn something about anything, i can always go to the library, or get some info link at the internet. history is not very interesting to read because of the length to read (i learned that in school) the drama is easier to watch and interesting, that’s why i said, ‘some input’, and i did not expect everything to learn from the drama itself. besides i am at the mercy of the english subs to understand the drama itself.

  151. 151 : tigerb Says:

    it’s a very good watch. the last episodes were more dramatic than the first ones building up the story. as usual, the veteran actors delivered well. this is the first time i’ve watched L, and i thought at first that his character was lame, and lame he acted, but in the last episodes, he was superb.

  152. 152 : N Says:

    So sad, I don’t want this drama to end. 🙁 The drama has grown so much on me. It was beautifully written. Superb acting by all the actors especially Yoo Seung Ho. His acting never fails to impress.

    This drama is very highly recommended! 🙂

  153. 153 : Simon K Says:

    I like both leads and I have high hope that this will be a very good drama but at the end I am slightly disappointed. The acting is good but the story is a bit lame. I keep waiting for the crown prince to do something smart to defeat the villain but nothing like that happened. The crown prince made many decisions to get himself killed but only survive because of luck. I wish the hero to be a little bit smarter than that.

  154. 154 : mel Says:

    Definitely in my list of top favorite historical drama, alongside Jewel in the palace, the moon embrace the sun, Jumong and the legend.

    Despite all of the drama flaws and controversy, this is indeed a high quality drama.

    The whole idea of the story, the perfect cast, the cinematography, the music, the sound effect, the powerful yet heartwarming lines of the crown prince absolutely make this drama very recommended to watch.

    Great job for all the cast and production staff. Kudos to the cinematography director, music director, sound director. As for the writer, for first project in historical drama, it is quite good. Hoping that you all will be a better writer and will wait for your next improved writing also.

  155. 155 : Ruler: Master of The Mask (RMOTM) OST and BGM | A Transient Wanderer Says:

    […] Ruler: Master of the Mask or Emperor: Owner of the Mask is my latest watched drama. It is a drama I have been waiting for since a long time ago after both @wow_kimsohyun (as Han Ga Eun) and Yoo Seung Ho (as crown Prince Lee Sun) confirmed as the main leads. […]

  156. 156 : Raion Says:

    I was looking forward to the end of this drama.
    But now that it has ended, I feel somewhat sad.
    I really love this drama.
    Love Kim So Hyun 🙂
    Has been loving her since she was younger and act as a younger version of the main character.
    And will always support her next project.

  157. 157 : candy Says:

    Love this drama and I dont feel bored watching it because every scene is intense. I love the character of Hwa Gun, her love for the Prince is selfless, I feel sad that she die.All actors are the best and also the soundtrack is cool.

  158. 158 : Mokoduk Says:

    @shiro. Yes, I think Hwa Goon deserves a special mention. She loved without being corrupted and subsumed in jealousy. It’s a special kind vision that a person submits to another, concerned only with the happiness of her beloved over an above her own. Beautiful.

  159. 159 : DeeAn Says:

    @simon K I agree with you

    The main lead actor was good.
    But I can’t feel the love chemistry between crown prince and ga eun.
    And the storyline is out of my expectation.

    Overall it was not supperb but it was just ok,not too bad 🙂

  160. 160 : Daisy Vega Says:

    Loved this drama! I am especially proud of the 2 leads. KSH & YSH have both been acting since they were little children and I consider their acting experience is better than many actors and actresses. Shoot and KSH just turned 18 y/o. The entire cast did a phenomenal job and I was glad to see an oldie, Hu Joon-Ho whom I first saw in HOTELIER (2001). Sincere thanks to all!

  161. 161 : ruby placheta Says:

    love it. more more more more. ilove you yoo seung ho and L..

  162. 162 : kdramaaddict Says:

    Not that amazing drama but still okay too me…

  163. 163 : kenzoismyHachiko Says:

    Love this drama!

  164. 164 : Candy Says:

    Well the last episode was so touching my heart. Especially at the end of the show. When Lee sun, Hwa gun and Ga eun’s father aprreared for the last time. It was making me cry. So sad that Lee sun must die. Over all…this drama is worth it to watch..will miss you all

  165. 165 : vote Says:

    Vote Ruler Master of the Mask for the top 8 best korean drama 2017.

  166. 166 : Sophie Says:

    I can say this is one of the best saeguk drama. yoo seung hoo is the best. actually I liked Kim So hyun, but her character here is less influential. too weak. I thought Hwa Gun would be one of evil woman here, but she sacrifices more for the king. even she was willing to die for the king. her love for her king is really sincerelly. I really cried when she die. I feel sorry for her. and Gon.. he love Hwa Gun, ㅠㅠ but he cant say anything till hwa gun die. I feel sorry for him too.

  167. 167 : Shariff Says:

    I really think this is the best drama I ever watched I like all the character in the drama the play a very big role I certainly felt so sorry for hwa gun she is the best character to me in the drama and in reality I fall in love with her am so sorry to say this but I really do and wish one they I shall meet her

  168. 168 : dandyoo Says:

    so sad drama. i like verry muchthis drama

  169. 169 : Kay Says:

    I loved everything about Ruler: Master of the Mask! Such an intriguing story filled with intensity. A nice romance between Yoo Seung Ho and Kim So Hyun as well a complicated bromance between Yoo Seung Ho and L. Thrills, drama, heart, romance. Absolutely wonderful!
