Lately, the protagonist has found himself increasingly troubled by his older sister's behavior. Though she naturally exudes an air of childlike innocence, she constantly seeks out opportunities for physical closeness that blur the line between casual affection and something far more intimate. Whether inviting him to join her in the bath or playfully licking a smudge of cream directly from his cheek, her bold displays of affection seem to escalate with each passing day. The tension reaches a breaking point one evening while he is watching television in the living room. His sister approaches him fresh from the bath, wearing nothing but a towel. As he nervously tries to avert his gaze from her unguarded figure, she fixes him with a deeply suggestive look and casually offers him permission to touch her. That night, lying awake in bed, the protagonist finds his mind consumed by thoughts of his sister. Replaying every lingering touch and teasing remark in his memory, his mounting desire finally drives him out of his room. He knocks on her door, only to hear her softly reply that she knew he would come eventually. As they step toward one another, the boundaries between them quietly dissolve.
