    Sound amazing. Hope it’s a nice drama. My favorite actress, Kim Hee Sun.

  5. 5 : Samantha Says:

    Another body swapping genre drama. Yes, Kim Hee Sun is awesome K-actress pairing with Kim Young Kwang. I love this mother actress, Kim Hae Sook. Strong characters with powerful voice in every thriller movies and family dramas.

  6. 6 : Chan Long Says:

    Look like revenge and mystery drama for me. Hope it’s a good one and thumb-up to 3 amazing “KIM”s.

  7. 7 : Great Fan Says:

    Yes, yes! Follow-up…..

  8. 8 : Typome Says:

    Don’t seem any nice drama during this times, hope it is a hit drama cuz I seldom see Kim Hee Sun in lawyer role but wait!, is it Kim Hee Sun or Kim Hae Sook is a lawyer in the drama? Love to see what is the turn-out?

  9. 9 : Auntie Ann Says:

    My gorgeous Kim Her Sun in new drama again. Count me in, btw your co-star is a young actor again. Lucky you!😍😍👍🙌🙌

  10. 10 : Samrah Atheed Says:

    (0s0) OOooh, she is amazing! She still look so young……

  11. 11 : Sakura G Says:

    Mmmph……! Interesting. I wonder how Kim Hae Sook swaps in Kim Hee Sun’s role. Sadly, this drama no lovelines between the leads.

  12. 12 : Connie Says:

    is this drama after Mr.Sunshine? wish it exciting than Mr.Sunshine. I like mystery and thriller than historical genre. Hope these two great actresses act well.

  13. 13 : Pingo Says:

    I like to watch dramas with 16 episodes or less and this is perfect for me. I like Kim Hee Sun, she always look sophisticated woman to me.

  14. 14 : McKlein Says:

    Give it a try. Few episodes dramas are less stress and tension than over 30 episodes given a lot of nonsenses dragging the story.

  15. 15 : Genie Says:

    Hee Sun is 10 years old than Young Kwang. Looks more like his older sis or mum than girlfriend. law partner sleeping on the sofa with a full open office…. make up artiste with wardrobe? lawyer ? colourful attire..? lawyers’ standard dress code is black.

  16. 16 : Genie Says:

    Certainly watching nevertheless because of Young Kwang!

  17. 17 : Yoona Says:

    In this drama, I have to admit Kim Hee Sun really look mature than Kim Young Kwang although he’s not handsome looking. Huhuhu! What to do? My favorite actress is getting older now, she shouldn’t pairing with those actors younger 10 years than her.

    Anyway. disregard about her ages but the storylines is quite straight forward and exciting to know what next plans for the convict Hwa Sa?

  18. 18 : Ashley Yau Says:

    Maybe they on purpose over-do the evil lawyer look more bitchy. Never see lawyers with hired personal make-up artists and stylists.
    Actually, she is a bad arrogant lawyer. She looked down on poor people and flatter on rich people. Don’t forget her bf is so damn rich, future owner of the hospital.

  19. 19 : Watson Says:

    Make it comes true, let Eulji stays forever in Hwa-sa ‘s body and Ki Yoo Jin better looks for younger and pretty girls. Eulji is too old for him.

  20. 20 : K-drama Fan Says:

    I just can’t believe Chu Young Bae is still alive and father of Ki Yoo Jin. Terrible man.

  21. 21 : Mikey Says:

    @K-drama Fan, are you sure Chu Young Bae is a real father of Ki Yoo Jin. Maybe there’s a twist, dead Ki-san looks resemble of Ki Yoo Jin. He puts the blame on Jang Hwa Sa because jealous of their relationship and he wanted badly to become the heir of Ki family.

  22. 22 : K-drama Fan Says:

    @Mikey, maybe you ‘re right. That’s why the beginning scene showed KYJ and JHS die together in the car? Is not a dream but hunts in Eulji’s minds. Hahaha….

    Any idea, who is this guy send the parcel to KYJ on his birthday date in Eulji ‘s house?

  23. 23 : Omar Says:

    Does anyone notice young Ki-san cast by Yoon Park ( he supposed to be Chu Young Bae which Hwa-san known)? Now, my question is who portray young Chu Young Bae? Are they twins? The grandpa is still alive, he should know who is his real son?

  24. 24 : алла Says:

    kim young kwang!! fighting!))

  25. 25 : Wei Says:

    Getting complicated now, hope Eng subs in episode 3 soon. Look like real Ki-san resembles Ki Yoo Jin but who is his mother???

  26. 26 : Elma Says:

    Which website can I watch? Dramanice haven’t out yet.

  27. 27 : Chan Long Says:

    Yes, episode 3 should not miss. CYB is the real culprit, accidently killed KS and put all the blames on JHS. Why will he done to JHS? Is KYJ his son or real KS ‘s son? KYJ looks alike real KS than CYB.

  28. 28 : Zanxie Says:

    Oh-gosh!!! that’s bastard is so abusive to women, how much I wanted to punch him on the face when he strangles Eulji neck? He’s psycho since he used Hwa-sa for his advantages.

    Yes, I wish Hwa-sa take her chance to revenge and a stop on him.

  29. 29 : Crazy Koreanfan Says:

    I like all the actors in this drama especially the 3 main “Kim”s and Jung Jaewon as Ki Chan Chung. He looks so cute kid but yeah, he’s already 24 years old. Why yellow-skinned people look so young than their ages nowadays?

  30. 30 : Mickey Says:

    The truths come-up in episode 4, Ki Yoo Jin isn’t Chu Young Bae’s son but real KI San’s. I am happy I am right. How can Ki Yoo Jin is so kind was that villain’s son.

  31. 31 : KINDERFUL WORLD Says:

    What a hilarious scenes when Eulji try to change back by the CPR device machine, then she realize she fail? She shocks KYJ when disclose she was Eulji while still in JHS body.

  32. 32 : Charlene Says:

    This guy is crazy sociopath, what ‘s the points to steal people wealth and still can’t be happy when the case is still going-on haunting him. Why his son is so young and he was already 63 years old? Didn’t he meet his sweet-heart when he was young? The writer is oversee the ages gap.

  33. 33 : mochim Says:

    Why someone say episode 4 is funny? I cry a lot in this episode when Hwa Sa reveals to her best-friend and her mother. It is so happy to see her mother after waited 34 years in jail while her mother became dementia, waiting her daughter to release from jail.

  34. 34 : Hate Bad Peoples Says:

    It is SO HEART-WRENCHING to know an innocent young woman been jailed for sooo long and in the death row sentence cheated by her moron bf. I can’t wait for his punishments.

  35. 35 : Coolman Says:

    I had watched many swapped Korean dramas in the past. But this one is begins with defibrillator machine……aish! I wish it work on me toooo…….hahaha!

  36. 36 : Kyla Says:

    I just don’t understand after 34 years passed, CYB still wanted to kill JHS so badly. Just leave her alone, she just an ordinary lady and he already premier. So sad; an idiot bf cheated, used and kill her in her entire life. The writer shouldn’t make him as a beloved father to his own son, he don’t deserve it.

  37. 37 : K-drama Fan Says:

    Yeah, that evil is going to kill one by one of them whose knew his pasts and not just for JHS.
    He is insane and nothing to do in life. He watches every of their steps.

  38. 38 : Yuley Says:

    @ Kayla,

    I’m same as your opinions. Why must he so heartless to her? She willing to give him the saving passcodes and commit suicide with him.

  39. 39 : Hannah Says:

    Hahaha! I’m laughing at this insane killer. Is he doing everything by himself for the sake of Damjang group? Deliver parcel to KYJ and killed Ma Hyun Cheol ‘s dog. He is super energizer as before.

  40. 40 : Momoko S. Says:

    I think Jang Hwa Sa is Ki Yoo Jin ‘s mother. Liked this show, story is actually simple and not perplexed but put in too many dreams confused me.

  41. 41 : Susannah Says:

    Really awkward, found his gf is his mother. How he going to face with her in future? Hope the endings isn’t sad, look like the mother and son die together.

  42. 42 : Rosmah Naj. Says:

    Ketiga-tiga aktis di sini sungguh mengkagumi. Menjadi minatku pada hujung minggu untuk menontoni.

  43. 43 : Tina Says:

    Kim Hae Sook as Jang Hwa Sa is super amazing. Now, she had to portray lawyer Eulji is really convincing. Kim Hee Sun needs to learn from her. She quite timid characters unlike Jang Hwa Sa.

  44. 44 : Nastywar Says:

    I prefer this drama than Mr. Sunshine. Bring back sad history of war will never today life.

  45. 45 : w122 Says:

    like this drama, very recommended, and kim young kwang so handsome…

  46. 46 : My way Says:

    Yooo! what happening now?

  47. 47 : Natalie Says:

    I’m confused. Both of them ain’t aimed killer but accidentally killed someone and famed others. I know Lee Kyung Young acts great as a villain in many K-dramas. Love the show.

  48. 48 : Mikey Says:

    Interesting weekend drama. Kinda fantasy revenge. Why would Chu Young Bae keep waiting to haunt her since 34 years, lol. He had many chances to kill her but why not until now? Its just crazy of him don’t like her to know he was Chu Young Bae but all his aides knew who was him?

    I don’t understand why Jang Hwa Sa doesn’t know she was pregnant? That bad dreams about her and doctors in the hospital is a horrific scene. Does he had to make so many failures ways to murder her, aishh…..

  49. 49 : Ashley Y. Says:

    Why the ratings fall so low in episode 5? I thought kill off Mr.Ma is good start to begin the revenge. If he not killed by Jang, sure Chu had intention to kill him. I do not understand why Dr Ki want to protect that person without know who she is? After seen the bloody heels behind the curtain.🤔🤔🤔

  50. 50 : K-Dramas Fan Says:

    kill one bad guy gave the ratings so low, why?

  51. 51 : Rihana Says:

    Isn’t it so shock to find out your gf turned to convict? From 3 years older to 30 years, how can I expect this drama will have romance. My poor KYJ, you don’t deserve both of them.

  52. 52 : Dandoffe Says:

    So disappointed the last 2 episodes lower ratings due the ridiculous crimes scene of Ma killing. How possible Eulji escapes from the crime scene so quickly. Wish it is an exciting revenge but its turned out stupid and ridiculous revenge. Not worth to watch anymore even three top-stars in the show.

  53. 53 : ****Go Gaga**** Says:

    Jang Hwa Sa is very stupid, again framed by Chu Young Bae. Maybe this her fates, she should die together with him.

  54. 54 : Mikey Says:

    Agree, agree. She has had to plan carefully to defend him, already known he is a cunning fox. What I seen here, she used Eulji’s body to go by flow without targeting her main point. So useless of her, no matter what forms she in?

  55. 55 : Vanilla Says:

    I hope this show won’t be like “Devilish Joy” which I have just finish watched. So suck, letting those betrayals get-away after living long-times with fake faces. Devil intentions people are always around but if the endings give light punishments to these people, villains will never learn a lesson.

  56. 56 : Josephen Says:

    Agreed with you, Vanilla about Devilish Joy. He don’t even remember, how he can revenge his aunt done to him? Jin Hyuk’s fans and viewers are more concern about their courting than revenge. The endings is really suck, no wonder the ratings is so low until end.

    Sometimes not about the poor performances of actors, mostly depend on the directors and the writers. Like this show, the director so poorly direct how the murder took place in episode 5 and 6? I don’t even know how it happened? Why the ambulance and police arrive so late?

  57. 57 : Yoona Says:

    Have any idea, who is Ki Yoo Jin’s real father and mother? Who bombed the hospital while Ki Yoo Jin’s mother gives birth?

  58. 58 : K-Drama Fan Says:

    @Yoona, bombed hospital is a dream haunting YJ and also assumption only. No know what is coming-up next? I believe YJ mother isn’t JHS and he was legitimate son of real KS.

  59. 59 : milk bottle Says:

    it’s a meteorite not a bomb. ratings are low because of the loop holes. just a waste of KYJ in this drama when he has so much potential for a romantic comedy. lack of exciting and credible story line. Devilish Joy was a let down which start off well with a good looking pair of leads but the draggy storyline and nothing exciting /entertaining killed my interest. The player similarly getting stale. At first it was about the male lead being a overly confident con man but now turned righteous (not for money anymore) and alluding to revenge? confused.

  60. 60 : Yani garsuniyantini Says:

    I can’wait to know how the last episode. Love to kim hee seon and all of the cast.

  61. 61 : Jessica Says:

    Poor thing. Look at the ratings getting lower because of that poor writer’s plot.

  62. 62 : K-Drama Fan Says:

    Ooooh…..cool!! Another fantasy elements added into it. How can this lousy writer thought about meteorite hits the hospital and everyone died except the tiny baby? The switching body also caused by the defibrillator possessed by meteor. Means KYJ isn’t real human. possibility he an alien to prove JHS innocent.

    I gonna nut if continue watching this show.

  63. 63 : My Cat Says:

    I don’t like this show, no realistic

  64. 64 : Nobo Says:

    Don’t get it. Who these people involved in tragedy? Something went wrong in plot of this drama. Why all these people helping CYB who is lowly dude at that times? So unlucky real KS died coincidence with his wife death strikes by meteorite, so the baby KYJ is the key to everything will be happen again after 34 years but 34 years? About the room no. 9, sure be superstitious.

    According to the show, Esther might be KYJ ‘s mother. She asked her friend, Morgan to meet again in 34 years. Why again 34 year?y

    Really interesting if you keen in mystery mixed with fantasy. I ‘ll patiently watch until endings to know why? Seem it is not many episodes and quite entertaining weekends dramas compare with other stressful and romance dramas around in this November, 2018. I love all casts in this drama, they are superb good acting not over aggressive.

  65. 65 : Detective Kim Says:

    Why the title given ‘ Room No. 9’? There must be a miracle happened in that room. Possibility, real KS swapped to KYJ and take revenge on CYB. That’s why HWS said the person died was KYJ and not real KS? They swapped during meteorite strikes. Story end.

  66. 66 : Kathleen JW Says:

    all the happened of swapping process in the beginning show was wasted and not the purpose to revenge that person put her in the death row and unnecessary site stories related to KYJ is absurd.

  67. 67 : Evonne Says:

    I feel this weekend drama is quite interesting compare with others except family drama, “My Only One”. These two veteran actress are good.

  68. 68 : Auntie Ann Says:

    Nowadays, too many common fantasy stories about switching and changing faces really confusing to cope with reality especially for my ages. I don’t understand why CYB waited so long to kill JHS if he can bribed all the authorities?

  69. 69 : Fanny Says:

    I still find this drama interesting than some of the dramas airing in November. Hope we can get the justices soon.

  70. 70 : Moorin Says:

    I’m so surprise that CEO Ki ordered CYB to fake KS identity. Maybe, he was the person who instructed KS to kill JHS together with KS in the car to hide his real identity because JHS was his girl-friend.

  71. 71 : OK OK OK Says:

    I am chasing this drama. Have watched ep 12. Very exciting to me. 😛
    The male lead Kim Yong Kwang got heights and looks. Very charming. Kim Hee Sun also very pretty & smart.

  72. 72 : Barbie Soo Says:

    Very satisfied with today episode 14. The break-up is a good lesson to Eulji to realize her wrongdoings and what she really want in her life.

  73. 73 : Fanny Says:

    I am going to miss this drama soon. Although it isn’t very impress plot but the casts in this drama are amazing in their acts. Lately, I feel the leads chemistry is getting good vibes after break-up. KYJ ‘s love to Eulji is truly amazing. He so easily forgives her and had been in love with her since high-school.

  74. 74 : OK OK OK Says:

    Just finished Ep 14
    do not miss this drama – very interesting and exciting. worth my time watching handsome Kim Young Kwang & pretty Kim Hee Sun

  75. 75 : Zara Says:

    excited for last 2episodes, hope Eulji not been killed by Chu Young Bae…..so intense

  76. 76 : My Life Is Kdrama Says:

    Going to miss this show but happy to see Chu Yong Bae going to end soon. Kim Hee Sun looked very beautiful and elegant in this show. I miss her soon.

  77. 77 : Sakesh Says:

    didn’t know that times passed so fast and this drama is going to end tomorrow. miss these three leads soon, unluckily the villain vengeance isn’t fully justify and sadly, JHW is going to die is really nonsense.

  78. 78 : Fanny Says:

    I don’t understand what make miracle happened by nature when the greedy CYB decided to stole the money from company. Why he had to wait 34 years to kill JHS when he had a lot of spare times to kill her? I am sure happy endings for Hye-ri and Yoo-jin but not for JHS, seem like she was fated unlucky woman, been cheated and accused as murderer, spent over 34 years in jail until she diagnosed with cancer and most sadly, her mom can’t recognized her as daughter.

  79. 79 : Maggie Says:

    Omg, so sad. She doesn’t deserve to die like that.

  80. 80 : LB Ping Says:

    I just wonder how this story can be happen if not because of the meteorite change their body? A sad unfortunate lady been accused as killer and jailed up to 34 years. I don’t think she is blessed with luck to seek her revenges against cheating bf cause eventually, she just 63 dies of cancer.

  81. 81 : kd Says:

    i already finished watchg this drama n i think i miss something
    the first one how did chan sung knows his father is chu yong bae?
