The setup sounds like every arranged marriage rom-com ever, then it immediately refuses to follow the script. Kobeni and Hakuya have chemistry that works because neither of them is trying to win you over, they're just two people figuring out what it means to live together without pretense. The show trusts its cast enough to let moments breathe instead of punching every joke, which makes the actual laughs land harder and the quiet conversations feel earned.
Kobeni's sixteenth birthday arrives with an unexpected shock: her late grandfather arranged her marriage to a complete stranger. She has no memory of ever meeting Hakuya, despite supposedly having met him long ago. When he and his peculiar younger sister Mashiro move into her house, things only get weirder, especially since her mother and her doting sister Benio hardly seem surprised. Hakuya shows an unsettling lack of emotion, and something feels fundamentally off about him and his sister. Mashiro obsesses over aliens and cryptids with unnerving intensity. Once the siblings start attending Kobeni's school, the mystery deepens. Small inconsistencies pile up. Strange moments accumulate. Kobeni finds herself caught between accepting an engagement to someone she doesn't understand and the growing suspicion that her fiancé and his sister aren't entirely what they appear to be. Comedy unfolds as she adjusts to these bizarre circumstances while slowly uncovering what makes Hakuya and Mashiro so different, and how it ties to the gap in her memory.
