All the cast worked really well on this drama, every actor matches well with their character, what makes it really fun to watch, but, it can be very frustrating to watch this when you think about the storyline. There are events that weren't well developed on the show, like how Seonjae dealed with his previous issues showed in some flashbacks or the reason for Soobin to do what he did in the last episode. Also, the last scene of the show is completely insane if you think about the events in the previous episodes, there surely were many other option they could've chosen.
There are chances of me rewatching the drama, but mostly for the acting, because I didn't like how the story went.
