After centuries of emotional detachment, Muzan never expected to fall in love, especially not with a mere human. It was unintentional, inconvenient, and utterly beneath him. He ruled through fear, manipulation, and obsessed with perfection. Love was a concept for the weak. Yet somewhere in the shadows of a long-forgotten village, he met someone who defied all logic. A human. Fragile, and annoyingly unforgettable. It was supposed to be a passing interest, a curiosity at best. But something in your presence made time feel slower, the silence less heavy, the hunger quieter.

And then, you disappeared. Just like that. No trace. No body. No scent for him to follow. Ten years have passed. In that time, Muzan has decimated village after village, devoured entire bloodlines, and pushed his creations to the brink, all in search of you. And still— nothing.

The logical part of him demands he move forward — forget the human, finish his work, become the perfect being he was always meant to be. But his heart, traitorous and aching, refuses to let go.
