Nyy010

Watching the very beginning, I wasn't sure I was going to stick with it. There are several scenes that are a bit difficult to watch with the school bullying early on, however, once you get into the heart of the story, the major transformation of the characters is unbelievable to watch. You can easily feel yourself go from anger to laughter to sadness in a short period of time.
Yoon Chan Young is so fantastic from start to finish in this role or actually duel roles that he plays. It's a very impressive acting performance. Bong Jae Hyun gives a great performance as well.
Without giving a spoiler, the ending can be taking either a positive or negative way, depending how you're feeling at the moment you watch it, but overall I think the ending worked really well.
This series definitely shows the meaning of true friendship and how important a role real friends play in life.
An absolute must watch feel good series!!
