After joining the drama club, Katayama found common ground with the aloof Nishida-senpai through discussions about costume design. One night, he opened a URL sent to his phone and received photos of the senior wearing a costume designed by herself. When he was asked for his thoughts on it the next day, he was taken to the senior’s house, where an erotic photo shoot began.

Uchino joins the student council to get closer to the admired president Megumi Hokura. While working in the council room, he notices her movements resembling masturbation but stays silent out of frustration. When her documents fall and he bends to pick them up, he encounters a lewd sight that escalates the situation. (Note: Some sources reference different scenarios like swimming club training under Captain Kurotaki or other club-based encounters; the series features multiple short, loosely connected school-themed stories involving uniforms and erotic tension.)
