Waiting for him when he gets home is Taiga, the ultra-perfect student council president at the school where Makihara teaches!! Even though he explains that there's no way a teacher and student from the same school can live together, somehow Taiga's very enthusiastic about it. What's more, Taiga finds out that Makihara is gay, and in exchange for keeping it a secret, he asks Makihara to practice sex with him...!? Student x Teacher's close-knit roommate love!!
