"Complex" and "Riu-san" talk about a coming-of-age party for Ruchi and Ruchi's friends. Ruchi tells Ruchi that he's going to be in Japan to take pictures for an event. He says that he hasn't spoken to Ruchi in a long time because of the events of the past few days, but Ruchi says he'll be able to talk to her when they're done with the event. When Ruchi asks if Ruchi is alone, Ruchi replies that he is. He's been hanging out with some of his layer friends, and they've just started a new group. He doesn't want to be a stranger to them, so he says that they'll talk when they get back to the apartment. He asks Ruchi if she's okay, and she says that she is, but that she has been wondering about something for a while. She tells him that she was in the same high school class as Ruchi when they were in their second year together, and that it's hard for her to get over the fact that she looks like a wimp. She says that Ruchi reminds her of getting married, which reminds her even more of being an old lady. She's sorry that she didn't say anything sooner, but she says she thought she'd tell everyone about the wedding when she was all together, so that no one would think she was talking about her. She also says that it took them forever to make a costume back in high school, and now it takes them ten years to make one. She feels like they are aging faster than they used to be
