Chou no Rikigaku, the third in the Keishicho Satsujin Bunsekihan series. I loved the earlier two so much, comparatively i think this one isn't that good, but it's definitely one of the better shows.
Love lasts forever is a very heart warming and fluffy drama. If you like cold male leads, you'll probably like this drama. Their romance scenes gave me butterflies. This drama would make blush and laugh.
