Sensei is on his way to the convenience store where Noriko works and, once he arrives, finds Kirin with her. The conversation quickly turns sexual, but Noriko, after Kirin suggests it, isn’t ready to lose her virginity since Kirin cried for hours after losing hers, which she vehemently denies. Sensei doesn’t want to comment on that since Noriko is still carrying her knife, but she thinks that every girl should carry one to prevent more cases of sexual assault. This causes Sensei to have flashbacks of the times he assaulted Yumi, pushed Miku too far and left a stain on Molly. As a result, he wants to change the subject which Kirin agrees with. Noriko suggests going outside and sitting near a burning trash can. Sensei shows concern about an open fire, but Noriko is confident in her skills to control fires. She mentions that Kirin’s only confident in giving fellatio, accidentally increasing the sexual tension between her and Sensei and reminds them that this convenience store isn’t suited for sex. Kirin, frustrated by Noriko’s chastity, demands that she should just do it already to make things easier for them. She intents to do that soon, but when Kirin demands to know when, she dodges the question. Kirin believes that she does this to hide the fact that she has a penis and Noriko, after allowing that discussion to go on way longer than she should have, assures that this isn’t the case.
Outside they start watching a promotional interview for Niki’s newest album. Kirin informs Noriko that she wants to sleep with her sister. Noriko doesn’t mind since, being the sister of a celebrity, she got too many posts with way more explicit content before she set all her accounts to private. The interview starts, but Niki cuts it short after the TV announcer questions her about her past, which she isn’t allowed to and doesn’t want to talk about. Once the interview is over, Noriko explains that idols have to avoid coming across as normal human beings since their popularity lives and dies with that, especially if they’re on the older side like Niki. She suggests to Sensei that he should follow her streams like Chika, whose messages she saw there sometimes. Sensei, after Kirin makes a sexual comment about her, accidentally lets it slip that he might have a close relationship with Chika but avoids answering any more questions to spare Noriko from any more pain. Kirin challenges him to a round of marry one, fuck one, kill one with Chika, Noriko and herself, stating that his answer would prove if he has something with Chika.
The ending depends on the chosen answer.
Fuck Kirin, Marry Noriko: Both of them are happy as Sensei feels about them as they want him to feel. Sensei feels sorry for Chika but takes solace in the fact that she isn’t there to witness this.
Fuck Noriko, Marry Kirin: Noriko is confused but stays optimistic, while Kirin doesn’t want him to marry her and has an emotional breakdown.
Kill Kirin: Noriko’s reaction are similar to the first one’s while Kirin, hurt by his decision, leaves. Sensei wonders if she really expected a better outcome for her, considering the type of person she is.
Kill Noriko: Noriko is heartbroken about being killed while Kirin is pissed of with his decision. If he decided to marry Kirin, Noriko additionally starts crying while Kirin calls this the worst decision he could’ve made.
