Well, I have no complaints about this drama as I knew this was not for me. Even my friends didn't recommend as they knew this is not my type of drama. But it was not so bad neither so good...This drama got such a big viewership internationally and maybe, it can surpass dramas like Goblin or Dots.
About the couple, I missed chemistry and felt lack of emotions . As a drama, I felt that this could be placed in the same class of itaewon class. So if you like that drama, go for it!!

The music is good ..could be added to your playlist. I don't know whether the psychological condition of the characters are portrayed medically correct . I felt a bit of artificiality in that.
