Pros:
-chemistry (10/10)
-ost is very very good (10/10)

Cons:
-they have a long break up period (broke my heart and they didn't even try fixing it fast enough)
-plot holes within plot holes (I know this is drama land, but like, this drama took it way too far)
-unrealistic actions (way too many)

I had to stop because of the break up period. I did some research, and it says they won't get back together for a while. :( I would call this a melodrama, which I do not like.

So, like I said, watch at your own risk.
