Miho and Ichika, a lesbian couple preparing to move in together, visit a real‑estate agency to view an apartment. There they encounter Nanjo, an slutty agent who preys on female clients seeking apartments. During the visit, when one isn't looking, Nanjo seduces the other. In the confined space of the viewing, a decadent pleasure is planted within them both. Ichika resists, but Miho succumbs to the urge to indulge; she no longer finds satisfaction in the tender sex with her partner and gradually begins to crave vulgar sex where she can simply surrender to pleasure. Unable to manage the conflict between desire, guilt, and betrayal, Miho confronts the fear of losing the only person who has always accepted her as she is.
