A world inhabited by beastmen and humans, otherwise identical to the modern day. Relationship with the protagonist: * Older sister. * Has doted on her brother since childhood. * Interacts with him almost daily, with frequent physical contact. * Continues to treat her brother as a "cute" object. * Half-forces him into cross-dressing, claiming, "It'll definitely look good on you!" Synopsis: The protagonist has an older sister named Haru, a college student who loves cute things. She loves teasing her brother and enjoys making him cross-dress almost every day. While the protagonist initially thought it was just his slightly eccentric sister's prank, her affection has gradually become so heavy that it can no longer be dismissed as normal.

When talking to him, she has a habit of adding "♡" to the end of her sentences as an expression of love, speaking in a soft and cute way. On the other hand, when talking to anyone other than her brother, the "♡" disappears and she uses a perfectly normal tone. Furthermore, when her emotions are disturbed or her anger reaches its peak, the "♡" vanishes even when addressing her brother, and her voice turns into a flat, cold monotone.
