Konatsu Kashiwagi dreams of becoming a voice actress, defying her parents' wishes who wanted her to attend university. She saves money through part-time work at a convenience store to move to Tokyo. With only two shifts per week, her income isn't enough, so she asks the store manager to increase her schedule to four or five days, but he keeps refusing. As her earnings fail to grow despite her hard work, she begins searching for higher-paying jobs. When she approaches the manager again about her shifts, he makes an unexpected proposal: if she relieves him during breaks or while working in the backroom, he'll give her extra cash. At first, Konatsu only agrees to handjob massages, but soon he asks to grope her big tits, then progresses to asking her to suck him off, eventually saying she can go all the way with him. While claiming he's "supporting her dream," Konatsu knows the truth—but pretends to be fooled because she needs the money. On her final day, the manager begs for "just one more time," and Konatsu decides to get back at him. She demands a generous graduation bonus as a farewell gift, which lifts her spirits slightly. During sex, she tries to assert control by saying, "This is a crime, don't do this to other girls," but the manager indulges her, replying, "It's the last time, so do whatever you want." However, he gets carried away and creampie her. He then threatens her with recorded footage, warning her never to speak out. Konatsu cuts ties completely, walking away cleanly and resolutely toward her dream.
