Yuu spots Fuuka in the hall and is about to talk to her, but then he notices she's crying. He follows her eyes and sees that she seems to be looking at their good-looking classmate, Mikasa. After school, Yuu ends up on pool-cleaning duty with Fuuka and Mikasa, but he can't stop wondering about their relationship. Meanwhile, Koyuki Hinashi, a childhood friend that Yuu lost contact with after she became a popular singer, finally calls Yuu for the first time in years.
