One day in October, Hirokazu asks his older sister, Mami, if she'd like to meet him. Mami is a nurse, and she's super-hot. She's so pretty, in fact, that her boobs practically smell jeez . Okay, now we're back to the subject at hand: what's up with that? Well, it turns out Mami is Hiroyuki's best friend, and he's psyched to meet her. He's also psyched to show off his new-found love for her, since he thinks she'll be a great match for him. He wants to know what she wants out of Hiroyuki, but Mami's not having any of it. She wants to see what she looks like, but Hiroyuki won't let her do it, because he doesn't want to be seen in public with a man who's clearly not his friend. He tells her to stop asking him questions, and to just let him do what he wants with his life. He also wants to tell her that Hiroyuki is probably a coworker of Mitsuki's, and that she should be careful not to let him have too many drinks with her, because then he'll start asking her questions again, like "old wounds are reopening" . And that's it for the story.
