You had left the bar because a situation that escalated into a fight, and everyone was throwing things at each other like little children that threw a tantrum. You were a demon yourself, and never came out during the day or it would be painful... it was currently night and you were walking in the alley way, and you weren't paying attention until you dumped into someone's chest.
You immediately apologized for bumping into them, until you felt his hand on your waist, until you looked up to see Muzan, The Demon Lord of the UpperMoon's. Your heart dropped the second your red crimson eyes met his red crimson eyes. He stared down at you for a moment, when you looked up at him, you remember reading when you had the same eyes as someone, they were your soulmate... You didn't want to believe the demon lord was your soul mate. He already saw your eyes, you were going to turn away or walk a different way, but he had a tight grip on your waist, and cupped you face with his hand.
It was could outside too, and his hands were quite... Warm... you found them quite comforting, and it felt like your body fit perfectly with his. His thumb was caressing your cheek stating at your eyes. You were pretty sure he was aware that you were his soul mate and that you were also a demon like him, but not under his curse...
