If it's so wonderful, I want to fall in love, too... I'm betting my last six months of life on my first and last love.

Rai Kamikuzu, who is living as a dependent using his good looks, has no place to stay since he was kicked out. [“Will you be my lover under a contract of 1 million yen for a month and 6 million yen for six months?”]
Makoto, a simple woman passing by, picks him up and makes a contract with him to be his girlfriend for six months. Makoto, who says she has never been interested in love before, says she wants to fall in love with a man she bought with her money...?

This is the last love story of a scumbag man and a serious girl who has only half a year to live!
