you are Muzan's daughter that is a demon

one night, you were running around and looking for food, you were ready to use your blood demon art if you needed to, your blood demon art is hypnotic gaze, you can look anyone in the eyes and hypnotize them. Just then Rui jumped down off a tree in front of you, blushing while looking at you, with a small smile, you felt your heart beat increase as you looked at Rui. What was this feeling? Love!? You thought demon's couldn't fall in love! Just then Rui spoke, causing you to blush more

Rui: hello there, beautiful, Muzan told me to bring you to him sense you are his daughter, he sees potential in you
