Yukimura's always taken care of his sick younger brother on his own, and it's finally pushed him to sell his body. But just when he thinks he can't go through with it, he's saved by the worst possible person, his former high school teacher, Kurosu, who already saw him getting assaulted once in high school and mistook it for paid sex. But when Yukimura tries to chase him off by asking if he'll be his partner, Kurosu takes him up on that and drags him to his house where they have their first night. After that, Kurosu offers to take Yukimura in as a live-in housekeeper and pay him for sex, provided he not offer his services to anyone else. Yukimura needs the money so he goes for it, but just as he starts to settle into their life together, Kurosu asks him when he's going to leave, and Yukimura realizes that Kurosu may already have someone else. Honestly, the misunderstandings in this plot are stupid, but Yukimura is a really strong and interesting character, even if I can't personally respect the teacher. Trigger warnings: attempted assault, sex work.
