Pros
The plot story is unique, but can be confusing sometimes. From the story, acting, music, etc, this drama is pretty good at the beginning, but can be boring in the middle especially if there are nothing that could grab your attention. For me, I keep watching it because I like bromance and this show have a pretty good bromance.

Cons
The only downside for me is the ending. If you don't like cliffhanger ending, then get ready for it. I'm hoping they have plan for season 2 because the ending is too vague.
