I really loved this Show, I seriously cannot understand those who rate the series negatively.
The series dealt with a number of problems that many individuals in societies suffer from, and which many people may not pay attention to, and I loved that very much. This is apart from the amazing actors and the wonderful chemistry between them. I really love Ja & First and I hope to see them in other dramas. If they weren't together.
As far as I remember, this is the fourth time I have re-watched the drama without getting bored.
