As a student at a university with high tuition fees and a family without the means, Shirosaki has to work diligently at a small grocery store. Although the income is not high, it helps her cover daily living expenses to some extent. Today is her first day working at the store, customers coming in and out in a hurry and there are all kinds of people, some cheerful and friendly, some difficult or abusive... but the most dangerous and frightening are the perverted individuals that Shirosaki unfortunately encounters. He always intentionally gets close and makes sensitive gestures touching her body, despite her attempts to avoid him, it only seems to excite him more. Taking advantage of the empty store, he plays the rogue, tempting her to have sex with him in exchange for a large sum of money. In a difficult situation, Shirosaki reluctantly agrees.
