Yukino has a boyfriend named Makoto with whom she promised to marry.
However, Makoto is a man of good family and they refuse the marriage with Yukino.
Then, Makoto's uncle, Masao, comes up with a deal. He would arrange the things to make the marriage possible if Yukino agrees to spend a night with him.
Yukino hesitantly accepts the condition.
However, it's a beginning of a devastating life...
