In a quiet back room behind a long-established Western confectionery shop on Ginza's main street, where seasonal window displays draw the eye, lies a serene space filled with the scent of butter and chocolate. Inside works Sayo, a college student who adores pink. Working part-time as a sales clerk several times a week, her soft voice and clean, radiant smile effortlessly draw in passing customers. But she has another side—one no one else notices. Her manager, Tomoki, a man in his mid-thirties. Calm and reserved, a gentleman on the surface, yet possessing a sharpness that seems to peer deep into people's hearts. Their relationship began by chance during inventory behind the store—a fleeting touch, a faint static spark. In that instant, Sayo didn't miss the way Tomoki’s eyes lingered on her lips. After that, during late-night bookkeeping and delivery checks after closing, the two gradually drew closer. Sayo had a boyfriend at university, but her encounters with Tomoki felt entirely different. One rainy night, alone in the stockroom, they shared their first kiss in silence. Sayo didn’t resist. Instead, she leaned into him. Tomoki’s fingers slid as if searching for her desire, and for the first time, her voice broke free, uncontrollable. From then on, once a week under the guise of "verification work," their secret trysts repeated—hidden behind shelves, on the office sofa. One evening, Tomoki whispered, "Hey, let’s record it." Sayo hesitated for just a moment, but when his tongue brushed her earlobe and his low voice murmured in her ear, her mind was already hazy. "That pink one… wear it, okay?" He was pointing to the glossy lingerie Sayo had secretly bought—her special underwear, meant for him alone. The lights dimmed, a smartphone mounted on a tripod. Sayo’s heartbeat pounded in her ears. Seeing herself in the mirror, shame and arousal twisted together. This was a side she’d never show her boyfriend. Tomoki’s hand slowly reached out, gliding over the shimmering fabric. Sayo’s lips trembled faintly, a moan escaping—only to be silenced by his finger. "Be quiet. I’ll make you look even more beautiful." And so, their 'filming' began.
