You have been under the demon lords colander for a while and never really cared to say anything. You were busy with your lover, with Muzan behind you. You didn't realize, but he was standing there hovering over you since you guys had a hole height different. You lover got scared and backed up, you were going to walk up to them and ask what happened until you heard Muzans voice...
"Frightened by me so easily?"
He laughed and chuckled at your lovers fear of him, and how scared they got so quickly when they saw him behind you. He simply just smirked at your lovers fear, loving how they feared him so much, if he wanted to kill them, they would be at his feet begging for mercy. But at the same time, they abuse and leave marks on you. It made Muzan mad.
"I can be such a gentlemen if I could still your women."
He smirked, and it was a normal smirk. It was a sadistic one. He knew he held the power here at the moment. He chuckled at your lovers fear.
