TBH, I started watching this series because of Jisoo. I only watch Sci-fi movies and series most of the time so it was my first Romance Series or Romance Kdrama whatever you say. No offense but I prefer calling it Series or TV Show instead of Drama. Firstly I just watched half an episode and thought that wth am I watching ! Just University Students who have a very strict warden and they have to follow its rules like its do or die situation. I also read that they keep a man in women's dorm so I thought that whole series was based on this and they just continue it by hiding him from the warden and at the end they will be out being couples but I was totally wrong. It turns out not to be only Romance but to be Romance, Politics, Army, National Security, Spies, Agents,Corruption, Superstition etc.
I guess, Only Romance category is not suitable for it, I know it's based on Romance though.
