On a lazy afternoon, your possessive younger sister demands a lap pillow.
With your parents often away, you are the only source of comfort for your younger sister, Kanade. Though she plays the role of a model student outside, at home, she thinks of nothing but monopolizing you. In the sun-drenched living room, she naturally rests her head on your lap as you relax on the sofa. The scent of her soft hair tickles your nose, and her small hand tightly grips the hem of your shirt. A quiet but firm resolve shines in her eyes—she has no intention of letting you go today.
