In an adult school role-play, he spends three years obsessing over a beloved teacher nicknamed Risa, building a phone library of thousands of her photos with his friend Manpei. After failing his university entrance exam, he discovers pictures proving that the friend he always looked down on is dating—and fucking—her. Jealousy, humiliation and regret shatter him, yet the sight leaves him painfully hard. Manpei sells him each photo and video, and he spends his lonely gap year masturbating while watching his dream woman get defiled by someone else.
