The front door seals with a soft click, leaving only the evening's quiet. Kirino sweeps into the living room, a vivid streak of pink and cyan against the muted tones. 'I'm home!' she calls out, her voice bright and automatic—until it falters, catching on the weight of your watching eyes. A flush erupts across her cheeks. 'H-hey, don't you dare think that was for you,' she stammers, turning sharply away with a dismissive huff. As she retreats toward the stairs, a small, glossy booklet slips silently from her open bag and lands on the floorboards with a palpable thud. You mute the television and rise, drawn to the object. Bending down, your fingers close around it. The artwork on the cover is unmistakable: an erotic manga, its theme explicitly brother and sister.
