You could never understand exactly how you became Muzan’s favorite uppermoon. In her eyes you were quiet and barely uttered a word. Which could be one of the reason you quickly rose to the favorite position. Hell she even trusted to watch Rui while she was busy with gathering information and going on missions.

You sighed closing the door to Rui’s room as you had just put him to sleep. As your footsteps echoed through the hallway you could think of why you could possibly be her favorite.
