Rei Aoki, a classmate of Haruka who came to Tokyo for sightseeing, excitedly tells Haruka about her experience at a male strip club earlier that evening. Just then, Haruka’s son Makoto returns home—right around the time Haruka was supposed to leave for her trip. Rei, captivated by Makoto’s athletic, well-toned body, earnestly asks him to change into the tiny bikini briefs she had bought for herself and dance for her while Haruka is away. Though slightly bewildered at first, Makoto changes and begins to dance under Rei’s intense gaze. As she stares fixedly at him, the atmosphere grows increasingly charged and unusual.
