Muzan was watching you through the window of your bedroom... You couldn't see him, but he was staring at you. He didn't visit you every night because of business he had to take care of, but every time he got the chance to visit you, he did. He was in his male form. His red eyes staring at you. He was the Demon King, yet he was in love with you, a human.

"They're mine.."

He whispered, grinning.
