After quitting her office job, Mai Satsuki joined a small theater troupe and now dedicates herself daily to stretching and vocal exercises. As she rehearses for the upcoming performance, she struggles with a particular scene requiring her to sway her hips fluidly, unable to control the movement properly, forcing her to pause practice. Witnessing her difficulty, the troupe's director gently steps in to guide her personally. Claiming it's to increase hip flexibility, he begins instructing her on a bed—spreading her legs, touching her groin—helping her gradually master the motion. Throughout this process, the intense, unfamiliar pleasure she feels and the director's tender care are vividly portrayed.
