    Another Love Story Series Again <3 <3 #JungHaeIn

  2. 2 : OK OK OK Says:

    i like Jung Hae In acting in
    Something in the Rain (jTBC, 2018) – i love Son Ye Jin &
    One Spring Night (MBC, 2019)

    As for Chae Soo Bin as lead actress in A piece of your mind, not sure I will like her or not bc previous project I did not watch bc so far could not attract me.

  3. 3 : Rhizokeel Says:

    #2 Chae Soo Bin is so good in I’m not a Robot, her acting is superb being a robot and a normal person. And also, she’s so damn gorgeous XD

  4. 4 : Lemon Says:

    AI? Like ‘My Holo Love’…

  5. 5 : Jukbang Says:

    One word .. six letter

  6. 6 : Darkgirl Says:

    Ohhhh, For the actress lead always always make me drop from the drama. Her acting always the same style, especially her voice. I don’t understand her feelings, her scenario in this drama .Anyway fighting. Keep fighting

  7. 7 : Tawney Love Says:

    The Swedish Lasse Lindh sings a track and I hate the style of singing. It’s like phrasing to a metronome; just awful.

  8. 8 : Ruby Says:

    I love Something in the Rain Jung Hae In & Son Ye-Jin are perfect pair, Hope tis A piece of Mind will have a happy ending. So far it’s a sad one😒

  9. 9 : annmasae Says:

    Love this drama. Both leads are great. I really like the OST songs. All so different. Unfortunately ratings are terrible but I like it very much.

  10. 10 : nischuu Says:

    I don’t expect this drama would give me this peace and consolidation at the same time. Love the two leads for emerging their story as one.

    The plot is beyond than what I imagined, the paced of the story kinda hooked me and how glad i was for giving this drama a try, such a worth to watch.

  11. 11 : Jukbang Says:

    Romance + classical song .. you will know the outcome

  12. 12 : Ivis Samantha Ortiz Monterrosa Says:

    4 chapters and already wanting to see more of this excellent work, a very beautiful and interesting plot, the cast of first. I hug you from Honduras

  13. 13 : Youta Says:

    the best drama ever <3
    i love this couple

  14. 14 : Jukbang Says:

    In real life Moon Ha Won should be called a psycho and indeed need a medical help.

  15. 15 : Revenge of the Cat Says:

    She’s all emotional relating to a computer program as if it’s the real person—Jo Soo. I was enjoying it up to that point. It’s now too weird.

  16. 16 : Momo Says:

  17. 17 : Laura Says:

    So far i like this drama and want to watch till the end. ..loves the characters.. They have good moment in this story… Lil bit slow but no prob.. I like when they’re together.. First the gilr fight for her feeling then the boy fight for his feeling after he realized.. Not complicated loved.. I like this drama.. And the girl not to possessive to get what shes feel

  18. 18 : narrice Says:

    what a romantic story, better than something in the rain. Feel sorry for the sort episode, because the rating, they cut it off. Don’t do the same to other good drama. Be more wise with the airing time management.

  19. 19 : Tayba Says:

    An absolute gem. Do not miss it.

  20. 20 : Lia Says:

    I love their chemistry! The story is all about healing and moving on… and with both of them together they were able to overcome traumas. Please give this a shot. This is by far the drama with sooooo many hugs…wholesome though 😊.

  21. 21 : Mimi Says:

    So damn good chemistry but sorry not the story too slow and just jump watch to latest 4 eps.
    Too bad good actor/actress nice view but not the story (once again) 😭 mianhe writer-nim
    Just love chae so bin and jung hae in but dont expect too high for romance. Both has angel smile please work again as a couple defenitly

  22. 22 : shiva Says:

    the leads were great but the story was so slow that it took me almost 3 weeks to watch it as I was keep falling sleep. 3/10

  23. 23 : Shirohana Says:

    It’s an okay drama,not so logic when you really watch this drama. No doubt the main actor was good but maybe not the right kind of drama for him ..to me its a so-so drama
