Souta has always looked up to his older sister, Miu, who has been a constant source of support and affection in his life. Living under the same roof, their bond is close, but Souta begins to notice a shift in Miu's behavior that makes him question the nature of their relationship.

One day, Souta accidentally discovers Miu's secret: she has been hiding a voyeuristic habit of watching him through a peephole. This revelation shatters the innocent dynamic they once shared, pulling both siblings into a tense and forbidden game of desire and guilt.
