I was already hooked when I saw rowoon in it but after awhile I was hooked to won jinahs acting too. It has a storyline that catches u by surprise. U tot it was the typical kdrama storyline. It was more than that. I guess I'm a sucker for character development type of dramas and this gets close to real life as it gets. The supporting cast were super charming and u just get sucked in the story unknowingly. And of course the ml and fl has amazing chemistry ..... I rewatched this too many times. Must watch for fans of melos
