Jun moves into his first apartment alone, thrilled to start as an assistant manager—until he discovers the building’s scandalous secret after spying on voluptuous Sumire and the other women servicing tenants. Far from alarmed, he’s drawn into their world as Sumire seduces him with her unrestrained passion, whispering that the suites exist purely for shared pleasure. Their heated nights blend duty with desire, leaving Jun breathless beneath Sumire’s expert touch, enslaved by her intoxicating taboo confession about the keys granting more than entry.
