It has been a while since Tsubaki has seen his sister, and now she's back in the States. She's so happy to see him that she asks him when he was last in Japan. He tells her that he's been living overseas for the past five years, and that he used to be friends with a girl named Mami. Mami used to live with him, but he broke off his relationship with her when he moved back to Japan. Tssubaki says that Mami seems like a nice guy, but that he doesn't fit in with his tastes. He says that he can't stand Mami's tastes, and he'd like to know why she broke off her relationship with him.
