In this short scene, Serina tells her friend, sempai, that she's back from her winter break with Mizukawa. They've been hanging out together all summer, and Serina says that she thinks they're having a good time. She's worried that Mizu-kawa might not know that Serina's girlfriend is there, but she assures her friend that she doesn't care. Serina also tells him that she wants to talk to Mizu about her crush, and that she needs to stick to her plan of getting her crush to marry Mizu. She also tells Serina that he gave her a present for her birthday, but that he didn't want to give it to her because they were "low on money" between the two of them. She says that he's not the one who gave her the present, and she'll be the one to get it back. She tells him to hold his breath, because there are people all around the place, and he can't make fun of her while she is wearing a swimsuit. She apologizes, and they head back to the apartment. She asks Serina if she can give her one more favor. She wants to thank her friend for spending two days with her.
