After moving into a new share house, a college student named Ryota Ochi finds himself living with two beautiful but demanding housemates. Rather than the cooperative living situation he anticipated, Ryota is ordered by the two women to do all the housework day in and day out. Frustrated by this arrangement, he reaches his limit and decides to move out. Just as he is about to leave, the two women offer him a surprising deal to stay: for every minute of housework he performs, he is allowed to have one minute of intimate physical time with them. This transactional arrangement becomes the secret rule that governs their unusual cohabitation.

The story follows Ryota, an attractive college student who excels at household tasks as a result of being the eldest child in his family, making him particularly useful to his housemates who exploit his helpful nature. His two housemates are named Momoka Hanaoka and Kanade Ayase, the women who initially boss him around before proposing the deal that changes the dynamic of the household. The share house itself serves as the primary setting, a private domestic space where these secret transactions occur behind closed doors.

The narrative develops through the ongoing exchange of housework for physical intimacy, with time as the central currency of their relationships. Ryota must navigate this tempting but complicated arrangement, where every chore completed earns him minutes of access to his housemates. The manga explores the power dynamics that shift as the three characters continue living together under this secret agreement. Written and illustrated by OUMA, the manga began serialization in September 2019 on WWWave Corporation's ComicFesta website and concluded in 2023. The story maintains its focus on the premise of transactional encounters and the evolving relationships among the three housemates bound by this unusual rule.
