Ueno Koji, a college student working part-time as a pet sitter, accepts an assignment to care for a rabbit named Aki-chan. Upon arriving at the apartment, he stumbles upon a bound, naked man in a closet—the man claims to be Aki, explaining that his abusive master fabricated the pet-sitting ruse to coerce Ueno into a sexual encounter, threatening retaliation if he refused. Though hesitant, Ueno engages in the act, displaying unexpected assertiveness that unsettles Aki.

Ueno departs as instructed but later crosses paths with Aki at his university. Aki reveals he defied his master, suffered violent punishment, and severed ties with the abuser. Now enrolled as a student at Ueno’s school, he seeks autonomy, subtly implying a desire to reconnect. Their ambiguous reunion leaves the future of their relationship open-ended.

Ueno shares no prior ties to Aki or the master. His pet-sitting role implies an assumed fondness for animals, starkly contradicted by this traumatic experience, which ultimately leads him to quit or lose the job—specifics unclear. His decisions during the coerced encounter and later interactions with Aki underscore a pragmatic empathy and adaptability in navigating manipulative circumstances.
