A MuTan story (Muzan x Tanjiro)(Demon slayer)

Prologue

Many years ago when Muzan and Tanjiro were newly Weds, Muzan had a deadly disease that was spreading. Tanjiro head a rumor while shopping, that there was someone who made a cure for anything. Tanjiro told Muzan about this and they agreed to go to this person and buy some of the cure.

Once they got the cure the person said to take it at home, so once they got back home they sat down and Muzan drank the cure. After a few seconds he started expecting extreme pain all throughout his body, falling to the ground, which scared Tanjiro.
He got down to Muzan worried and scared trying to help him. Muzan fell unconscious. Tanjiro picked up Muzan and carried him to their bed.

After the sun set Muzan woke up but was now a demon. Tanjiro ran over to him hugging him. "What happened and why am I so hungry?" Muzan asked. "You fell asleep after drinking the cure I'll go make you some food." Tanjiro said kissing Muzan on the cheek before going to the kitchen.

Muzan looked in the mirror and realized he was hungry for blood. He didn't want to hurt Tanjiro so he opened the window and ran. A few minutes later Tanjiro came back with the food but was terrified to see Muzan wasn't there. He ran over to the bed and began crying.

Four months later

Demons have beg to multiple in result creating demon slayers. Tanjiro decided to become a demon slayer. There was news or the demon king being in a nearby forest. Tanjiro went with a few other demon slayers but split up to cover more ground.

Tanjiro saw a tall slender figure drawing his sword but soon realized it was Muzan. He stood there in shock. Tears began to form in his eyes. Muzan soon noticed Tanjiro and began walking over to him. Tanjiro dropped his sword and ran to Muzan tackling him into a hug crying into his chest. Muzan began to comfort Tanjiro while crying as well.

"Why did you leave?" Tanjiro asked. "I didn't want to hurt you." Muzan respond looking into Tanjiro's eyes. "I know you would never hurt me. Please turn me into a demon." Tanjiro said surprising Muzan. "No I don't want to hurt you." Muzan said back. "You won't and I want to be with you forever no matter what you do or who you become." Tanjiro said snuggling more into Muzan's chest. Muzan relectently agreed and began to turn Tanjiro into a demon. Tanjiro began to be in pain but fell unconscious after a few seconds.

Muzan picked him up and brought him to the infinite palace and placed him in his bed. Muzan got in bed next to Tanjiro, kissed his cheek, then cuddled up to him.

Unfortunately Tanjiro didn't wake up for 10 years. In this time Muzan created the 12 moon ranks and made Tanjiro upper moon 0. Once Tanjiro woke up Muzan barely ever let Tanjiro leave the room and on the rare occasions that Tanjiro did leave the room he was still in the infinite palace next to Muzan who was VERY protective of him.
