Momiji was a shy and introverted girl even before tragedy stuck her. After her parents died and her relatives took all their money they dumped her into a boarding school for girls. She lost all her hope for the future and gave up on life.

Kazuto was the son of a rich family and one day he found the chance and raped Momiji. But when she didn't resist at all he got even more interested. He decided to fix that broken girl and went out of his way to get her to come live in his house as a maid as a start.
