Seriously, the cast, the BGM and the storyline.. were just amazingly perfect.
The personalities of the cast were thought through until the end, the BGM fitted perfectly and the whole plot was done nicely.

It was my first Drama. I totally recommend that to everyone.
You'll laugh a lot and cry a lot. It's a very good drama. :D

The OST is one of my favourites until now. :)

[off topic]And I choose a Hotel in Ikebukuro when I went to Japan in 2009.. because of this Drama. :D[/off]
