Minami tells us that she's been working at the gym for a while now, and that her supervisor is her "sen ior" , who used to train her when she was a new employee. He's called out to her when he sees her at work, and she tells him that she doesn't know what to do. She's actually not very good at swimming, so she switched to the other side of the gym. Minami's shocked that she would be so good at something as simple as swimming, and wonders if she'll be able to teach her supervisor how to do it.
