Housewife Ren lives a cold, distant relationship with her husband and decides to renew herself by visiting an esthetic salon. However, her indifferent husband doesn't seem to notice any change. One day, after seeing a recruitment commercial for the salon, Ren decides to become an esthetician herself. On her first day working, she becomes flustered when touching a male client's body for the first time, overwhelmed by its warmth. The client notices her reaction and begins demanding massages around his genital area, then direct stimulation of his penis. Ren endures it, telling herself "he's a customer," but his demands continue escalating further and further.
