mdl users are giving this drama a lot of bad reviews but for me this was one of the best dramas ive ever watched.
yes, the thriller part of the story is messy and can get quite confusing, it definitely could have been formatted or blended in better with the romance side. but i viewed it as something that kept you on your toes while still enjoying watching the leads fall in love.
the two lead actors did an amazing job in this drama, and their characters' loveline was so cute. their romance was just so beautiful, and both characters helped each other heal. seo hyunjin's acting was on another level.

also none of the side characters bothered me, because usually in every kdrama there's 1 or 2 side characters that i dont like. in this one, each had their own story so i was never annoyed when a character appeared on screen. almost each character learns new ways to heal and deal with their obstacles.

many have said here that this drama was mediocre. but for me, i loved almost every second of it. i loved the interactions between characters, i love the small lessons you learn. i loved watching the healing of these damaged people.
