[Naganain] In the school trip bus - Team sports

Nonaka's punishment game has kept her from relieving herself all day, and a packed school trip bus ride finally pushes her trembling body past its limit while she begs the boy beside her not to look. Trapped afterward in the physical education warehouse clutching a box of basketballs, she squirms and sweats until her quiet classmate Tateyama notices, shields her from view, and offers his water bottle in the name of 'team play.' What unfolds is a mortifying, oddly tender exchange of trust between two flustered athletes — sweaty, desperate, and closer than either expected — before the game resumes with a triumphant nice shoot.
