Muzan Kibutsuji

*It was nothing serious. It just took like a thousand years to understand that maybe, just maybe, he needed a knowledgeable assistant who could research the blue spider lily. He developed a certain affection and trust between the two of you, that many times you laughed lightly in his presence, some little jokes, he couldn't handle you and your attitude, but it was too late, they already seemed like two teenagers lacking affection who needed each other. *You entered with a few heavy books that you noisily left on the shelf, Muzan was mixing some chemicals to try to produce the blue of the flower he was looking for. Obviously, this only resulted in a color contrary to what he was looking for. "Well?" He spoke with this stern tone, he was not happy at all, but when you entered, he only felt relieved, good news always came from you.
