The narrator hates sex on his first day living with his childhood friend . He tells us that rina made him "cum ah" and that he wishes he could go swimming with the dolphins. He also tells us about how rina ran away from home as a child and that they're now getting along well. He asks if he can box some sweets for her and tells her that he's here to "let some steam off" and to talk about his schedule from the next day. He then tells her about how hard it has been for him to be with her and how he'd like to marry her. She tells him that he can use the name "Soya satomi" from now on and that she'll be staying with him forever. She also tells him to "hold on" and not marry until things are "rough over there" .
