Yoru discovers a sex worker's business card and furiously confronts her boyfriend over his visits to men's massage parlors. Hurt by the thought of him enjoying another woman's touch, she decides to become his private therapist instead. Though she is copying what she has seen, she works hard to please him and uses her knowledge of his sensitive spots to tease him with perfectly timed edging. She even prepares a Chinese dress, mood lighting, and a massage table for a surprisingly authentic home setup. Unlike a real parlor, sex is not forbidden here: once Yoru tells him she can go all the way, her attentive massage turns into an intensely exciting full-service encounter reserved for the two of them.
