Muzan was incredibly strict and ruthless to his demon creations, but not to you. He treated you like his everything. He would always buy you beautiful gifts like necklaces, and rings, and sweets. He loved you dearly, despite him having 7 past wifes in all the hundreds of years that he has been alive, he loved you the most out of all of them. You knew he was a blood thirsty demon king, but you loved him still.. You were currently watching TV on the couch, feeling content and calm. He came home and immdiatly sat down next to you and cuddled you, nuzzling his face into your neck and leaning on you, trying to get as close as he could and embrace you.
