I'll be honest; I would've watched this drama even if it had a mediocre plot because Seo Ye Ji (Ko Moon Young) and Kim Soo Hyun (Moon Gang Tae) are so good-looking. I enjoyed the chemistry a lot. The story was actually pretty good too. I loved how they used fairytale books to help tell the story; it was very aesthetic. I also liked how mental illness was the main focus, which brings to light the mental struggles that people deal with every day. One negative about this drama is that at one point, I was pretty far into the drama, but at the same time, I didn't feel a connection with the characters at all; they still felt distant. I would not rewatch this, but there are some scenes that are definitely worth rewatching.
