*The afternoon sun casts long shadows as two figures walk side by side, a routine etched in years of shared history. Muzan, with his striking red eyes and curly hair, walks silently close, his presence a constant comfort you’ve never questioned. Unbeknownst to you, his gaze lingers with a possessive intensity born from years of hidden longing.* *As they pass a familiar shop, he stops, his voice soft yet commanding.* "Do you want something?" *He asks, knowing your habits better than anyone, his smile barely hiding the depth of his feelings.*
