## Summary

A flashback from six months ago narrated Yume shows how she used to worship items given to her by Mizuto. In the present, Yume sniffs Mizuto's boxers and then, in a state of panic, drops them on the floor, and astoundedly asks herself why she did that. Fearful that she'll regress to her old "introverted" self and what consequences would befall her if Mizuto found out, Yume decides to return them at the best opportunity. When the time comes, Yume sneaks out of her room to return them to Mizuto's room, but comes to find out that he had hoped to do the same with her bra.

Afterward, the two perform rock-paper-scissors on who goes first for their impromptu family meeting, and Yume goes first. She claims it wasn't her fault and that she merely reverted to her old introverted self. Mizuto then has Yume explain what she meant by that, and she sheepishly answers that she used to treasure things given to her by him. Hearing this makes Mizuto seemingly blush, but he denies the fact. As for his explanation, Mizuto claims that he believed she wouldn't believe him even if he told her. How Mizuto got Yume's bra was he saw it in the dryer after he took his shower, and when he went to pick it up, their father walked in on him. Despite Yume not believing Mizuto, she gives an eerily similar story about she retrieved his boxers. Once they settle everything concerning the altercation between them, Mizuto suggests that they allow a single demand from the other so long as it doesn't infringe on the other's social norms. Yume agrees to it, which seals the deal.

On her way home from school, Yume spots Mizuto with a lad at a Wicky-D's and immediately thinks the two are on a date. What further frustrated Yume was that the girl looked similar to her back when they were dating. The following day, Yume asks Akatsuki about her opinion on it, and she thinks of it as a momentous occasion for Mizuto.

Later that day, Yume finds an extra pair of shoes at home and believes the shoes belong to the girl she saw him with at the restaurant. Hence, Yume contacts Mizuto and has him do a favor for her so she can confront the girl she suspects is in his room. When Yume believes the coast is clear, she rushes over to Mizuto's room, and before she can open it, Mizuto exits it. A conversation starts between them about the girl Yume believed to be there, which raises concerns about Mizuto's supposed lecherous behavior or whether their house is haunted. In his room, Mizuto believes that the whole "paranormal" incident is related to the same girl that he went to the restaurant with.

A flashback reveals that the girl Yume was Akatsuki in disguise, and she wants to marry Mizuto so she can become Yume's sister. Akatsuki then explains all the personal things she'd like to do and experience with Yume when they're sisters. Furthermore, Akatsuki follows Mizuto throughout the day straight to his home. Mizuto later contacts Kogure about this and asks for his advice. Kogure tells Mizuto about Akatsuki's immense infatuation and her passion for clinging to things she holds dear until "kaboom". An example of the "kaboom" was when Akatsuki was in middle school; she had a boyfriend to who she was passionately devoted. In the end, it killed said boyfriend's mood of her, and she broke up with her. Kogure suggests that for now, Mizuto stands his ground with Akatsuki and that he does not waiver with her. If, however, she becomes too much for him to handle, they'll have to take a more direct approach, which Mizuto would want asap. So Kogure suggests that Mizuto have Akatsuki give up her interest in Yume and suggests he tell Yume something.

Later, Mizuto visits Yume's room to exercise her punishment on Yume for possessing her underwear, which is to go on a date with him.
