In this chapter, the protagonist attempts to teach his friend Yui Hiiragi how to orgasm. She tells him that sex is the "essential part of sex" and that he should "swallow your insides" . He tells her that he was her first partner and that she slaps him when he says that he is happy. He says that they should have sex in six months and that the time should be spent giving each other the "best love" they could ever have. The protagonist then tells the story of the author of "super popular boys' manga" who was recognized for her talent by a major publishing company and who is now working on adapting her manga to an anime series.
