Yua Mikami serves as the manager for her class's soccer team, which had a 3-day, 2-night trip during the summer holiday for practice, and Mikami also went there. Previously, she had a relationship with a shy classmate after discovering that he had a secret crush on her; she took the initiative to help him satisfy his desires right in class. It seems that her lewd nature did not change when she was with the soccer team members during the trip; after a classmate secretly watched her change, instead of scolding him, she proactively helped him satisfy himself just as she had done before.
