Ema and Aizawa worked together at a convenience store four times a week. They were close and seemed to have mutual feelings for each other. One day, when a member of the night shift came down with a fever, the manager asked Ema to fill in. Aizawa volunteered, saying, "Ema is a student and shouldn't be working night shifts, so I'll do it," but since Aizawa was already scheduled for the morning shift immediately following the night shift, the request was rejected, and Ema ended up taking the shift. Ema complained to Aizawa, "The manager is creepy and I can't stand him," but Aizawa couldn't do anything and went home, leaving the two of them alone. Afterward, Ema's virginity was taken in the convenience store's backroom, and in a single night, she became the manager's meat toilet.
