  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:

    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.
