My favorite drama of all time!
I started watching it and then in two days i already finished it, i rarely watch a non-romance kdrama but this is absolutely worth it.
I loved everything about this drama! the cast, the music, the story, and the art at the end of the episode. don't  forget the bromance, it's so good in here!
Just watch it, you will never regret it! i never found myself bored watching it, when i was close to the final episode i was so sad, even now i'm sad because i wanted to watch it forever,
