A stalker targeting a female college student, Akari, attacks her on a dark street and imprisons her in an abandoned building. He convinces her that "it's dangerous outside" and that "he's my only ally," and so they begin living together. In exchange for food, he demands sexual satisfaction and makes her suck his dick. He feeds the hungry Akari, instills her with trust and love, and repeatedly has sex with her and cums inside her like a lover. They spend their days in the empty, closed space, distracting themselves with recreational sex. Akari begins to think about spending the rest of her life here with the man she loves. And so the 185th day arrives...
