I first approached this drama because sungjoon played the lead roll. However, I was surprised how much character development went on in the first 3 episodes only so I got the hint something was wrong. Nonetheless, I still extremely liked sungjoon's role I felt he was very down to earth. However, some parts were unnecessarily dragged such as the problems with the mom and dad, and their sister, which i felt was just annoying in general. I liked how things turned out in the ending, except there should have been more parts where we see the main roles spend more time together as they did in the first few episodes when they confess towards one another. All in all, the drama was pretty addicting and I recommend it :)
