This drama is great for those people who were just starting to watch this kind of genres. The story and the characters were great. But Minwoo's character development was poorly executed. He could've stayed as a protagonist. They didn't even give him a one whole episode to explain himself. They think that a very small backstory would justify his actions. Plus they deleted A LOT of scenes just to create a loop hole which will give way for s2. I personally don't think that "popular" dramas need s2, it will definitely ruin the story ( just like love alarm) S2 was actually very unecessarry because the drama was already good as it is.
