  3. 3 : OK OK OK Says:

    After reading the synopsis, I wonder the leads will end up together or not??
    Or just like Kim Hee Sun in Angry Mom, both leads never in courtship at all & didn’t end up together.

    Really? Isn’t Ji Woo too old to pass as a 20 year old?

  18. 18 : Dy.K Says:

    The trailer promisingly funny. Great cast line. Familiar with this writer drama but not fond of.

  19. 19 : annmasae Says:

    @g14 #12 Totally agree about the screen writer. All her dramas My Daughter Seo Young, Shining Inheritance, 49 Days were so well written. Her last drama Two Weeks was written in 2013 so I’m glad she’s finally written another one. Can’t wait!!!

  27. 27 : dream Says:

    I see this drama because my favorite actor is Lee Sang Yoon, but i think he should match with other actress not Choi Ji Woo. Hope that he will not end with her.

  35. 35 : HOPE26 Says:

    I like the story so far.. It is not predictable but i’m hoping to see Cha Hyun Suk & Ha No Ra together in the end.. Ha No Ra doesn’t deserve to be treated that way by her husband.. especially the Son, its sooo annoying why there are still children like that who doesn’t know how to respect their parents!

  36. 36 : hiravee Says:

    i love the story line

  37. 37 : Nina khalid Says:

    I just love choi ji woo.talented n still amazingly beautiful at 40 yrs old.

  38. 38 : didamalek Says:

    Never miss Choi Ji Woo’s dramas and films so far. I am a great fan of her. Hope the story ends with happy ending.

  39. 39 : Dee dee Says:

    Good so far

  40. 40 : Lila Says:

    I would like more this drama if it would be more original, without the old cliche about confusion of having a terminal ill that make the characters have changes in their behavior and feelings based on something untrue and generate misunderstandings.

  41. 41 : AnnieMac Says:

    The plot is interesting. Great acting Sang Yoon!!!😍😍😍

  42. 42 : Shirley Says:

    Good drama, great actor and actress, interesting story.

  43. 43 : AnnieMac Says:

    The high rating of this drama in a pay TV channel shows that it’s very entertaining…. Daebak!!! I so adore Sang Yoon… Hope his hair style will be changed soon 😍😍😍!

  44. 44 : Birddybuddy Says:

    I’m addicting to this drama ❤️😆 it’s just Daebak.

  45. 45 : Fanfanfan Says:

    I am watching this drama for one reason, CHOI JI WOO! love you beautiful lady!

  46. 46 : princess Says:

    watchin bcos of lee sang yoon n choi ji woo….

  47. 47 : Cherie Says:

    Can some1 confirm about the terminal illness.

    Ha no da is not sick?

    Thanks a million

  48. 48 : Faye Says:


    Ha No Ra is not sick. There was a mixup at the hospital and she was given the diagnosis of another patient called Han Ora. She’s perfectly fine and should live for a long time.

  49. 49 : Naga Says:

    Cute drama.

  50. 50 : tiex Says:

    hhmm..interesting enough to be watched so far.. Funny and make me curious about the next episode. Unusual but interesting story,..and Lee Sang Yoon acting is great,..
    Hope their keep the good work,..until the end of the story..

  51. 51 : OK OK OK Says:

    Choi Ji Woo really maintain her beauty very well 😛
    Hope she ends up with Lee Sang Yoon

  52. 52 : Carmen Says:

    This drama got me too…OMG what a really good acting on those actors yes all of them are doing a great job……did you notice that her son is like her just look at somebody dancing and do the moves…love it I hope she can do something for her….that husband do not love her from long time ago….I hope she leave him be….and work for herself she really deserved….after having a baby really young…she can do it now…

  53. 53 : Adeul Says:

    The title is misleading because of their use of the term “twenty again”. It has no relevance since there is no quintessential age for a student.

  54. 54 : Adeul Says:

    I like the drama.

  55. 55 : amaal Says:

    i like it

  56. 56 : Ve Says:

    Hope happy ending

  57. 57 : Adeul Says:

    What is the song at the end of last episode? Anyone?

  58. 58 : Pretty Butterfly Says:

    I love Lee Sang Yoon! He is sooooooo handsome!!!!! Can’t take my eyes off him!!!!!! Muaaaahhhhhh





  61. 61 : AnnieMac Says:

    Ep 6 is cute 🙂 LSY is groovy 😍😍😍! So cool….

  62. 62 : annmasae Says:

    Loved Ep 8 on dramafever.
    Choi Ji Woo is finally standing up for yourself.
    Hope she doesn’t end up with her husband because of her son.
    She is doing a lot of the things that she missed while taking care of her family. She needs to live for herself now.

  63. 63 : theworstme Says:

    Interesting storyline. Really love it. 😊😊😊😊😊

  64. 64 : Sia Says:

    Ep8… one word: DAEBAK!!!

  65. 65 : ellen Says:

    haha… nice film with interesting scenes. The man who ride the bicycle around the school. He tease the hat of his girlfriend while he ride his bike. He is 38 year olds, really?. Or he also came back 20 ages like his friend… :):) It was made impression on me.

  66. 66 : Juliet Says:

    This drama is becoming very interesting. So far, so good!

  67. 67 : AnnieMac Says:

    Omo, the rating is increasing !!! Super entertaining, so far 🙂 just finished watching ep 8. LSY is the best in shifting emotions. I find him sooo cute 😍😍😍 fighting, Sang Yoon!!!

  68. 68 : AnnieMac Says:

    Omo, Omo, I didn’t notice…. It’s half-way through 🙁 happy ending, please….

  69. 69 : cris Says:

    love to watch ha nora dance and i am sure her fans who are late 30’s to 50’s want to see more of her dancing skills in the next episodes. the love story of her and cha hyun suk shoud be sweeter now as ha nora will realize
    that her stalker loved her since high school. kudos to the writer/pd and staff. love this drama

  70. 70 : Imah Says:

    I enjoyed watching this sdrama so far. CHOI JI WOO is always the best among the best n versatile actress too. OMG cant just take off ma eyes from watching her. GOOD come back with good story line indeed. Luv the drama so much.

  71. 71 : Rosana Says:

    I like LEe SAng Yoon especially his dimples.

  72. 72 : Cassie Says:

    Am so glad she started to stand up for herself. SHe was an abused wife from the very start. She was a doormat with all those verbal abuse from a cheating husband. this is worst than being a battered wife. Now that she has found her passion again am sure she will soon find her happiness. Choi Ji woo plays Nara so well as always a great actress becomes the character. Same goes with the Lee San Joon and the 2 second leads. Nice drama.

  73. 73 : Greenshine Says:

    Like ^_^

  74. 74 : OK OK OK Says:

    Ep 8
    Love to see Choi Ji Woo dance on stage but sad that it is to be continued…. 😛

  75. 75 : Ann Says:

    Love this drama….hope Choi will be with Lee Sang Yoon!!!

  76. 76 : Sabrina Says:

    Full of laughter, love and care & all we want…good & happy ending^^

  77. 77 : Marie Says:

    Can’t wait for Episode 11 & 12 next week!!!! Hope she divorced him!!!! and Hope Chan Hyun Suk will find out about their divorce so that he can confessed his long kept love to Ha No Ra and that Min Soo will find out that his dad is cheating on her mom!!! I love this drama… sad 6 more episodes and I have no more drama to watch!!!!

  78. 78 : OK OK OK Says:

    i want Choi Ji Woo to end up with Lee Sang Yoon too because her husband did not treasure her at all. Take things for granted. 😛

  79. 79 : Pretty Butterfly Says:

    I enjoy every episode of this light-hearted drama especially because of my MAIN MAN, Lee Sang Yoon!!!!
    Now, how come so little is revealed about how HNR ended up married and pregnant with KMS so quickly?! Even her best friend didn’t know anything about it except that she left for Germany in a hurry?! She left her beloved grandmother all alone, old and had to fend for herself?! Why?????

  80. 80 : Hiang Says:

    In this drama, choi Ji woo is not acting like a 20 years old, she act her age. a 40 yrs old mum going back to school.
    So the age is not a problem at all. she didn’t act like she is 20 yrs old.

  81. 81 : Go Girl Says:

    Both Lee Sang Yoon and Choi Ji Woo are excellent in this romantic comedy. LSY is just so cute and hilarious portraying a “weirdo” professor. Love you, LSY!!
    All 4 main male and female leads are so funny!

  82. 82 : Faye Says:

    Shouldn’t the TMNS rating be 6.9%? A 1% difference is a lot.

  83. 83 : AnnieMac Says:

    Sang Yoon has his own unique way of expressing his feelings to Ji Woo in Ep 12 without being cheesy 😊 that’s very appropriate in their age. That’s so very realistic! This is getting romantic 😍😍😍. I can sense that the drama will end happily 😄 I hope I am right….

  84. 84 : AnnieMac Says:

    I am still wishing for the drama to be extended. This is a feel-good drama and I haven’t seen much of LSY’s dimples just yet 😄😄😄 love you Oppa!!!

  85. 85 : Naga Says:

    Nice drama. LSY is so petty and so sweet!

  86. 86 : Pretty Butterfly Says:

    Just finished watching Eps 11 & 12. 👍👍👍

  87. 87 : joyce Says:

    its a good drama, choi ji woo portrayed her character so well so do with lsy and all the casts. what i wanedt to see in the coming episodes is how cjw and lsy be a romantic and a happy couple who find true love in the en

  88. 88 : Rizal Says:

    Pliss…ha no ra♡cha kyun suk happy ending ^_^

  89. 89 : Zen Says:

    Ha no ra – cha hyeon seok berharap bahagia

  90. 90 : Dini zen Says:

    sorry wearing Indonesian. but the episode of 14 tonight expecting a romantic ha no ra and cha hyeon seok ^^v

  91. 91 : Pretty Butterfly Says:

    I’m just done watching Ep 14 and I have this to say about this drama – “I love this drama! And, because of the lead A1 male actor, LEE SANG YOON!!” 😍😍😍😘😘😘😘

  92. 92 : naisy Says:

    Pleaseeee.. Only two episodes left, give us some romantic scenes from Cha Hyun Suk and Ha No Ra. That’s the only thing lacking here. Thank you

  93. 93 : winnie Says:

    Looking forward to last 2 episodes this week. Great chemistry. it’s interesting even in the absence of romantic scenes which is understandable because Ha no Ra is still married to Kim Woo chul .
    I hope they end up together in real life.

  94. 94 : sara Says:

    i like this drama good plot good actors and interesting

  95. 95 : Bernice Ponce Says:



  96. 96 : AnnieMac Says:

    I always love scenes in Kdramas that involve the pulling of girl’s arm by the guy. LSY did that to CJW in the later part of ep 14…. Soooo flawlessly executed by oppa that you can feel him imposing his feelings to cjw 🙂 Cool 😍😍😍

  97. 97 : AnnieMac Says:

    I would be so happy to see more episodes. The planned love triangle by ha no ra’s ex-hubby should be fun to watch and I don’t think the remaining two episodes will be enough to elaborate that and the expected romantic scenes of LSY and CJW. Please…..

  98. 98 : AnnieMac Says:

    And hope to see new hairstyle of LSY. The one that will make him look more dashing 😍😍😍

  99. 99 : Ve Says:

    S3moga happy end

  100. 100 : joyce Says:

    yes , pd we want to see lee sang hyun eyebrows. it has to be a suave hairstyle especially when they have a kiss scene.

  101. 101 : Naisy Says:

    Please have some romantic scenes between Cha Hyun Suk and Ha No Ra. And let that bad husband repent and pay for his shortcomings. Would be better if you could extend more episodes so we can see sweet romance between CHS ad HNR, so we can see HNR when she graduates and finds herself a job. Good luck, such a great drama!

  102. 102 : Jalex Says:

    One if the nicest drama showing in the second half of 2015. I loved the leading couple, they exhibit great chemistry and looked so sweet and beautiful together, childish and even shy at times regardless of their age and yet caring for each other deeply without showing it too much. I’m a fan of them already. Not forgetting how no ra’s self discovery tells us how we sometimes lose ourselves in our hectic lifestyle but it’s never too late to change your lifestyle and pursue things you like again. I also liked how the ‘villains’ woo chul and yee Jin changed for the better after seeing what real love should be like from hyun suk’s unconditional acts to no ra and the people she loves. A heart warming and matured rom-com. Sure hope there will be a happy ending tonight!

  103. 103 : Naisy Says:

    Finished Ep 15. Ha No Ra such a disappointment, how can she turn down Cha Hyun Suk..? Cha Hyun Suk, you are too good for Ha No Ra who is saying she does not love you she has too many alibis also in loving. Just go to Sang Ye, she’s the one who loves you so much. Good CHS let go of Ha No Ra, so proud of you. You don’t deserve a woman who does not care or love you!

  104. 104 : LY Says:

    I’ve just finished watching the final episode. This is really one of the best dramas for 2015. Highly recommended. Thank you to all who were involved in the making of this wonderful drama.

  105. 105 : annmasae Says:

    great drama. good ending. screenwriter So Hyun Kyung triumphs again.
    can’t wait for her next drama. Besides this drama, she wrote Two Weeks, My Daughter Seo Young, 49 days, and Prosecutor Princess.

  106. 106 : ann Says:

    Love the ending so sweet… looking forward to see both leads soon again !!! Fighting

  107. 107 : Pretty Butterfly Says:

    Love this feeling good drama! 😍 I adore you, Lee Sang Yoon!!!! 😘😘😘

  108. 108 : Bissky Says:

    DAEBAAAKKK!! I LOVE THIS DRAMA SO MUCH!!! So funny and makes me scream with the romantic scenes. So in love with the ending ❤❤❤

  109. 109 : Juliet Says:

    Very nice drama! Great chemistry between the two leads. I hope they can be paired again in the future. This is a highly recommended kdrama!

  110. 110 : AnnieMac Says:

    Wonderful ending, Daebak!!! And I was soooo happy to see another hairstyle of LSY towards the end of ep 15 😍😍😍 congrats to the team… Truly a job well done!!!

  111. 111 : OK OK OK Says:

    Choi Ji Woo & Lee Sang Yoon ends up together – love love love 😛

  112. 112 : OK OK OK Says:

    Wow, congratulations to the good ratings because its a TV pay-channel 😛

  113. 113 : Fern Says:

    A series of fun and good.

  114. 114 : rachanee Says:

    i like this korea drama twenty again very much

  115. 115 : Jibiko Says:

    I think this is a very good actor, played very well, especially choi ji woo her all the show has been very active.

  116. 116 : january Says:

    I watched this drama because of star jiwoo otherwise I’ll not be watching it at all. I enjoyed so much that i think this drama deserves awards.

  117. 117 : Anne aragones Says:

    Its a good, deana with excellent scriptwriter and director. Its fun there’s no biring episode. U gad a wonderful time watching after coming from work. They nade a good job including the actresses and actors. The best choi ji woo in portraying her role and also lsj.

  118. 118 : lovekdrama Says:

    Omg! Love this show! Must must watch!!! Funny and romantic… they’re so sweeettttt

  119. 119 : Myvilvil Says:

    One of the best dramas I’ve seen so far.

  120. 120 : Choi Soo Be Says:

    I love this drama : story, casts, and ending are very nice.

  121. 121 : Mfh Says:

    CHOI JI woo puts me OFF the show. Too bad, like the actors tho. She is one actress I cannot stand watching, sorry.

  122. 122 : Snow Says:

    [email protected], same here. I love the male lead, but cannot stand watching Choi Ji Woo….not even a little bit. Something about an older actress trying to act like someone younger…..no.

  123. 123 : Muriel Archer Says:

    Just completed watching this very wonderful series. The acting of all the cast was simple great. I loved the main leads and for me the first time of seeing Lee Sand-Yoon and Choi Ji Woo. I am now going to check for other series and films for both of the actors. Thank goodness for Netflix I now watch mostly watch Korean and Taiwan productions. Thank you. 👏🏻🤗♥️
