Rin doesn't know which girl to choose, so the show destroys him for it. The first half plays romance comedy straight, then the second half pulls the floor out, every choice he makes has real weight, and the girls stop being options and become people with their own breaking points. By the end you're not watching a harem, you're watching the wreckage of one.
Rin lives a quiet life in a world where humans, gods, and demons now share the same space after barriers between realms crumbled. His routine shattered when his next-door neighbors turn out to be divine and demonic royalty, complete with their adult children in tow. Both Sia, the god-king's daughter, and Nerine, the demon-king's daughter, harbor feelings for Rin from a past encounter he doesn't remember. Add in Asa, a charming upperclassman who enjoys needling him, and Primula, a mysterious girl he finds abandoned in the rain, and Rin suddenly finds himself juggling unwanted attention from every direction. What starts as romantic comedy chaos gradually deepens. Rin discovers each girl carries her own secrets and struggles tied to the integration of their worlds. His choices begin mattering beyond just dodging confessions: friendships fracture, loyalties splinter, and what seemed like harmless school romance becomes something with actual weight. The tone shifts between light comedy beats and genuine emotional stakes as Rin realizes he can't keep everyone happy, and someone will inevitably get hurt.
