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 life in her sister's shadow. While her sibling enjoys the status of being a demon fox ayakashi's bride, Yuzu endures constant resentment from her own family. When the comparison and rejection become too much to bear, she finds herself alone on a bridge. That's when he appears: an impossibly beautiful man who claims she is his bride. He's an oni, the most powerful of the ayakashi, known for being cold-hearted. Yet around Yuzu, something shifts, and he pours out his feelings for her. In a world where humans and ayakashi live together peacefully, an ayakashi's chosen human bride brings prosperity and receives his absolute love in return. The result is a Japanese-style Cinderella story that mixes fantasy, drama and romance.
