Heian Era, 902.*

Muzan was an ill, noble man, as weak and fragile as a newborn lamb, having to continue his clan.

His relatives tried anything. Found women. All older than him. All married off to him. Muzan had five wives by the already early age of nineteen. Five women he hated. All the same. The women asking when they would have sex with him, which they never got. Muzan never got intimate with them. Hell, the second the wedding was over, he always went to his estate, alone. Where he had doctors take care of him. He never wore the rings he was supposed to wear, never held their hands, talked to them, hell, thought about them. For him, his "wives" were just five strangers. He didn't care for anyone really.

That was all until he met someone. The person that changed everything.

You.

Muzan really couldn't care less about what the doctors told him. Never took his medicine. Never obeyed. He wanted to stay alone. All the time. Read books, sleep. They needed someone to deal with this, have patience. You were a kid's doctor. You had bratty kids throwing tantrums, and were known for your patience and kindness.

Perfect for him.

When Muzan was told he'd get a new doctor, he was furious. The day you were supposed to meet him, he was already ready to yell.. but then..you walked in his room.

He stopped. For one second..Muzan let his guard down.

Despite not even knowing him, you came in with a kind, patient smile. You were seventeen. Younger than him. You were kind, sweet. You were beautiful. Drop dead gorgeous. Lovely.

You were patient with him. You listened at his complaints about pain. You listened to him reading out books he liked.

You cared. And he felt something for that. He didn't know what. No, he knew. But he didn't want to admit it.

It was love. It was new.

His wives were furious. Jealous. How in just one month, you had softened such a cold man up. You had to keep boundaries, since he "belonged to them". And when he heard they would change you because you were "distracting".. Muzan couldn't take it anymore.

He married you. The first marriage he actually proposed in. The first wedding he actually kissed his bride in. The first time he stayed in a home with a wife of his. It was no doubt, he loved you. Only you. Whenever people asked him, Muzan would say "I have one lovely wife." One. Where he had six on paper. He always wore a ring. Your ring. Everything was perfect.

Since you were his wife, they got Muzan a new doctor. Though, this one seemed to rather..use him for experiments. One medicine became another, and Muzan was suddenly.. strong. He could walk, even run by himself. He didn't need constant care. He just couldn't go out to the sun.

The "medicine" from the doctor had made him a demon. The first demon.

You accepted it. Now that he was healthy..he gave you everything he couldn't. Only you. Even more love, so, so many more gifts and a baby. Yes, a baby. He impregnated you, now that he could.

The other wives were fuming. But they came out with an plan. A cruel, bittersweet one.

You were on your eighth month of pregnancy. They all acted sweet, yet did something not to sweet. Mixed poison in your food. You were poisoned.

The night he came back..there he saw you. On the floor, barely alive. He didn't know what was louder. His cries, or the pained screams of the other five wives when he killed them brutally.

✧

That was what brought things now. You were barely alive, so Muzan gave you his blood, to make you a demon and make you survive. Yet your fragile body couldn't take it. And that's why, now you were laying in a futon, barely living and him making new medicines to heal you. Muzan slaughtered everyone. The other wives, the relatives, the doctors. Just not you.

It was nighttime, the only time Muzan could open the windows so he wouldn't burn. There he was, over at the table, mixing doke medicine with his blood. He gave you his blood slowly for you body to take it properly. Though, you were barely awake.

I'm not done.
