Living under the same roof as roommates, spending day after day with someone who is neither lover nor family. As encounters multiply in shared spaces like the entrance, bathroom, and toilet, awareness grows naturally. Yet they remain just roommates, without a private relationship. They don't deeply understand each other's lives or feelings—close in proximity, yet somehow distant. In this ambiguous space, the time spent alone together as man and woman always carries subtle tension and curiosity. Even within the ordinary routine, unexpected allure lies hidden.
