I have been a fan of kdrama since 2009 so I sometimes become choosy on watching kdramas these days. However, this drama surprised and impressed me in a lot of ways. Story wise, it has a great plot, well-written, and balanced. I really wanna commend the casting, because the lead couple turned out to have such a great chemistry. Their friendship is different, and on screen, they seemed to help each other become the best in their character. Not gonna forget the other casts, of course, because they also made the drama more fun. Oh and the OST? One of the best! I even bought the OST Album cd :) and even when I finished watching it, I tend to miss them and watch different scenes over and over, as well as the behind the scenes. Sorry if you feel I am exaggerating, but this is really how I felt after watching the drama. My attachment to them has become too much that I couldn't even move on lol. Worth your time, swear! Also, this is a comeback drama for seo in guk <33
