## Summary

During a late-night rain storm, Yume receives a text from her mom that she'll be home late because of the typhoon. Yume replies that she understands and wishes her well, but moments later, she spots a cockroach in her room and freaks out. After barging into Mizuto's room, she tries to find the right word to explain the thing that invaded her room. When Mizuto figures out what Yume found, she freaks out as the mere name of it shocks her. Despite spraying her room with pesticide, Yume shares the bed with Mizuto, and the two bicker for a while until they fall asleep. Mizuto wakes up amid his sleep and sees how close Yume was to him and struggles with his feelings about their previous relationship with her, but he does his best to forget them.

The next day Mizuto and Yume get into an argument over the cockroach in her room. Their parents then note how they're arguing like a married couple and sequentially announce they will visit Mizuto's side of the family for Obon. As the only fun thing to do in the area is swimming in the local river, Yuni insists that both Yume and Mizuto buy swimsuits for themselves. Before they leave, Yume insists that they wear disguises for a more incognito approach. Begrudgingly, Mizuto agrees to it, and when Yume tries on some swimsuits, Mizuto, under pressure from Yume, gives his opinion on one suit that she was trying. It leads to an embarrassing situation between them, and ultimately Yume decides to purchase that swimsuit.

Walking home, Mizuto and Yume pass by the wall where they had their first kiss. While standing and staring at the location, the wind blows off Yume's hat, and when Mizuto tries to catch it, he comes close to Yume's face, making it look like he tried to kiss her again. Although Yume prepares herself for the kiss, Mizuto instead flicks her on the head. At home, Yume returns the book Mizuto lent her, and it's noted by their parents how awkward the two were acting with each other as if they were a couple. Yume then snaps at them, denying the fact, but Mizuto internally notes how their parents are teasing them being a couple proving to him that they see them as siblings.

The following day, Isana visits Mizuto and Yume to watch a movie with them, and Yume is jealous that Isana watched the movie on Mizuto's lap. Yume depicts the situation as Isana gradually trying to get Mizuto to propose to her, to which he'd respond yes too. Once the movie is over, Isana asks for Mizuto's opinion on the movie, and he answers that it was interesting and goes on to explain his favorite part of it. Their conversation then escalates about blatantly the movie using the gender swap troupe. Hearing the spirited conversation between Isana and Mizuto has Yume jealous again. Mizuto then asks for a drink from Yume, so she serves it in her mug, and Mizuto casually drinks it. Isana then mentions that Mizuto had an in-direct kiss from Yume. From there, Mizuto falls asleep in Yume's lap, and Isana is then tempted to kiss him; however, Yume admonishes her from doing that. Then, Isana reveals she's considering trying a friends-with-benefits relationship with Mizuto, which earns a rebuke from Yume. Before Isana leaves, she comments that Mizuto lying on Yume's lap is like a brother-obsessed sister allowing her brother to sleep on her lap. Although Yume denies that notion, when Isana leaves, she's tempted to kiss Mizuto, but stops herself from doing it. She also realizes forgetting her feelings would be for the best. Afterward, Yuni curiously asks Yume about Isana and Mizuto's relationship while casually mentioning Yume will probably find a boyfriend soon. On the other hand, Yume admitted that she couldn't picture dating anyone other than Mizuto.
