A girl spent her whole life being told she wasn't enough. Then an oni decided she was everything. The show doesn't treat this as a fantasy premise to get cute, it's studying what happens when someone finally gets unconditional love after a lifetime of none. Yuzu doesn't need saving from her family. She needs to believe she deserves the devotion she's being offered. That's the actual story.
Yuzu has spent her entire life in her sister's shadow. While her sibling basks in the status of being married to a demon fox ayakashi, Yuzu endures constant resentment from her own family. When the weight of comparison and rejection becomes unbearable, she finds herself alone on a bridge at her lowest point. That's when he appears: an impossibly beautiful man who claims she's his destined bride. He's an oni, one of the most powerful ayakashi in existence, known for his cold demeanor and emotional distance. Yet around Yuzu, something shifts. He offers her something her human life never could: unconditional devotion and a place where she truly belongs. Their arrangement challenges everything Yuzu thought she understood about love and worth. As she navigates this supernatural world where humans and ayakashi intertwine, she discovers that being chosen by the most formidable creature around might be exactly what she needed to finally choose herself. A romance built on genuine desire rather than obligation or family pressure.
