In this short scene, Tachibana tries to get her brother, Hiroyuki, to come to the blood science lab to get his test score. She's worried that he's going to cheat on the test, but he says he'll try harder the next time. He's also worried that his mom is going to quit her job and start making lunches for him, so he wants to make sure he doesn't have to deal with her. He tells her to just pretend that the test didn't happen, since she'll be able to make her own lunches. He also tells her that his four-year-old son and his six-year old son are both in school with the same teacher, and he hopes they'll get along well. Hiroyuki says that his family is growing, too, and that he hopes to get along with his new family. He asks if she's done her homework, and she says that she has. He then asks her if she has solved any of the problems in his book. She says that he probably hates her anyway, so she'd rather not have any trouble with him. She also says that her skin made contact with him, which is creepy, but that she doesn1t want him to get any ideas about her or her family from that contact. She tells him that girls get worked up over little things, too.
