I waited for this drama, excited for a new role for Jung Hae In, a darker role that isn't his usual melancholic nice guy that he is already so good at. Jung Hae In's acting in D.P. was superb and I'm so proud of him for challenging himself, I hope he keeps it up. Everyone else's acting was really something as well, they all really immersed you into the drama and it all felt so really. The topics that it dealt with are really important and can be sensitive to others so be careful before you watch it. It's obvious things like this have happened before and I'd bet they are still happening which upsets me, hopefully the drama will bring light to it. Every episode is very watchable and despite the bullying you actually find yourself enjoying it and can't wait to move onto the next episode. There are comedic moments that are a breathe of fresh air during the serious scenes. I really recommend you watch it because it's impressive and informative.
