To be honest, this is one of the best korean drama I've watched BUT I won't repeat watching it again.

The story, the cast and the soundtrack are great. I know that IU acts well and convincingly, but she did extra great in her role in this drama.

I won't watch it again because this drama is too heart-breaking to watch again. I'm so surprised I surpassed those heavy drama scenes. I cried myself like a baby even on those little scenes.

Please do watch this drama. You won't regret it.
