A girl married to a demon who's supposed to eat her, except he's terrified of losing her. Two people loving each other so hard they can't admit it, speaking in opposite languages, each convinced the other wants something horrible. The tragedy isn't that one of them might betray the other, it's that they're both already betrayed by their own fear.
Mashiro owes her life to Shuten Douji, a powerful demon chieftain who pulled her from certain death years ago. Now seventeen, she understands the unspoken agreement between them: she's promised herself as sustenance for the being who saved her. When they marry, she approaches the union with grim acceptance, ready to fulfill her debt through the ultimate sacrifice. But Shuten Douji has spent years protecting and caring for Mashiro, his feelings deepening in ways that complicate everything. He has no appetite for consuming her. He wants her alive, whole, and by his side. The problem is neither can say this directly. Mashiro interprets his hesitation as reluctance to claim what's rightfully his. Shuten Douji misreads her resignation as willing self-sacrifice he can't bear to accept. Their love becomes a painful contradiction, each trying to honor what they believe the other wants while desperately wanting something else entirely. Caught between tradition, devotion, and terrible miscommunication, they must find their way to honesty before their good intentions destroy them both.
