START-618 Hagoromo Tenjin (22), a recent college graduate and office worker suffering from homesickness while living alone for the first time, is betrayed by the owner of a diner—whose food reminded her of her mother's cooking—and finds herself at his mercy, toyed with however he pleases inside the shop after closing time.

Ui, an office worker exhausted by the unfamiliar pace of city life, finds her only solace in a diner that reminds her of her family's home cooking. One night, worn out from work, she dozes off at the shop; after closing time, the owner assaults her and confines her in a dim garage to silence her. Trembling in despair, she becomes the target of the man's twisted sexuality and raw desire for dominance, as he begins to control every aspect of her life—even her meals and bodily functions.
