In this chapter, we learn that the two of them have been friends for a long time, and now that they're married, they've been invited to a summer festival in the U.S. They're both psyched to be there, but they can't help but notice that the other guy, katsunaga, is also there, too, and that he's been bugging Yui to invite him to the festival. Yui says that she's invited him, but that she doesn't know how to respond to him, so she'll have to wait until the festival is over before she can invite him. She's glad to see him, though, because she wants to look as good as she can. She asks him if he got the invitation because he has the same name as her, and he says that he never knew it, but he did get attached to her because they have the same last name. He tells her that he killed his parents because they didn't treat him well. He says that his parents tormented him and broke him, and in the end, he killed them all. He's not a criminal, he says, but as a human being, he deserves to be punished for his actions.
