Satoshi is quickly drawn into the rhythm of his sister's life, from the cozy living room where they catch up, to the soft, shared moments in the same bedroom. The connection between them deepens, especially during late-night talks and shared meals, where the affection and care she shows him become increasingly personal. The bond is not just familial—it's a blend of admiration, affection, and a slow-burning attraction that neither of them can ignore.
