My sister-in-law moved in today...

Hitomi moves to Shungo's parents' house due to her husband Shungo's work. Hitomi is worried about her new life, but Shungo, a workaholic, doesn't care about her at all. Her brother-in-law, Masahiro, noticed Hitomi's loneliness. Masahiro helps Hitomi in place of his older brother who doesn't even clean up his belongings. However, on the day of the move, Hitomi, who was defenseless, was raped by the lustful moving workers. And when Masahiro sees Hitomi hurt, he tries to comfort her somehow...
