I looked forward to this drama mainly because of the cast. At first I thought it's more like a thrilling ,mystery, drama. But after watching this one i didn't feel any of those. Before watching every episode I hoped something exciting was going to happen ,but nothing.
MY PERSONAL REASON TO DISLIKE
1.They fooled me with the amazing cast
2.I didn't like the way it ended. It can be far far better.
3.The way the second leads ended up together. I hoped she could be with her first love.
4.There was not a single element that made me feel excited or thrilled.
5.I somehow predicted the ending ,but i hoped it would not be the case.
6.In order to have a happy ending they sacrificed a highly potential story.

I'm totally regretting it.

POSITIVE
There is nothing much to say but
1.music
2.visual
3.cast

if you are looking for a drama to kill your time its good
IF YOU NEED SOMETHING EXCITING,THRILLING GUYS JUST SKIP THIS ONE.
