Crunchyroll is simulcasting the anime and describes the story:
When his father remarries, Yuta Asamura winds up sharing a roof with his new stepsister, Saki Ayase, the hottest girl in his grade. Carrying the scars of their parents’ troubled divorces, they vow to maintain a respectful distance. But what starts as cautious camaraderie blossoms into something deeper from shared experiences. Is it admiration, familial love, or something more?
