In this short scene, Hiroyuki and his sister, Kiyoko, return from their five-day trip to a tropical island, where they are reunited with their brother, Hirohito, and their mother, Kishida. Kiyoko tells her sister that she has improved in her teaching skills, and Hiroyuki thanks her for her efforts. He also tells her that he is now in a band, which means he is in the "hotter social zone" . He asks his sister if she is in a "rebellious phase" , and she responds that she is still cute. She asks him what he has told her about boundaries in high school, and he responds that he has. He then asks her to help him, his mother, and sexual saayas in school, so that he can tell them about boundaries. She responds that her face is still "cute," but she is not yet ready for dinner. She tells him that she will be back in five days, and that she wants to swim with him. He is nervous, however, because he has been a member of the swimming team, but he says that he will not lose against him in the upcoming competition.
