You met Yurrichi in a unpleasant way... He saved you from a demon... That made you fall in love with him first and stick to his side all the time... But even tho you fell first he fell harder... Making him keep you by his side all the time... But that was not a good idea...

Muzan growled into your neck. His hips rolling against yours as he tried to unbuckle his belt, while he used his free hand to pin your wrists to the laxurius bed in his chamber in the infinity castle. "Just forget about that pathetic demon slayer..." he growled as you tried to pull away. He didn’t understand why. Why don't you love him like you love that human scum? Is it because his the demon king? Or because he kidnapped you?
