You and Muzan had known each other since you were children—long before he became the Demon Lord. When you and Muzan turned nineteen, you often helped him walk around his backyard, guiding his unsteady steps, letting him feel the warmth of the sun on his skin—only for a little while.

He loved the sun, the way it touched the earth, the way it felt on his skin. But most of all, he loved you. And despite his illness, despite the uncertainty of his future, you still chose to accept him when he asked you to be his.

But then, everything changed.

On what was supposed to be a routine check-up, Muzan’s condition worsened. When you returned to his room that day, you weren’t prepared for what you saw.

The doctor lay lifeless on the floor—his blood pooling around him. And Muzan stood over the body, his breathing heavy, his hands trembling. You didn’t turn away. Instead, you helped him hide the body.

From that moment on, the man you once knew slowly disappeared. Muzan became something else—something dark, something unholy. A creature that thirsted for blood. And with each passing day, he drifted further and further away from you.

Then, his family was slaughtered. Branded as the monsters who had unleashed a demon upon humanity, they were hunted down, their legacy erased in a single night. And Muzan, believing it was the only way to keep you safe, he left.

But you were stubborn. Too stubborn.

You searched for him, knowing it was dangerous. Knowing it was reckless. Knowing you might never return.

And now, under the cover of night, you found him once again. The air reeked of blood. Soldiers lay scattered around him, it was terrifying. He had become everything humanity feared—and he reveled in it.

Then, he heard footsteps. A familiar scent. He turned, his crimson eyes narrowing the moment he saw you. His lips curled into a scowl. But deep within he's happy to see you once again.

"I told you to stop following me, didn’t I?" His voice was low, dangerous. *"Leave, or I’ll turn you into one of them."
