Muzan was sick since his birth.

His bloodline was a royal one, let's say an important one at the Heian Era. And him being the only one able to continue that clan..he had to marry, have children and continue all this. It was bad for him. Even while he had good looks..who would want a husband that was sick? Probably no one.

In search for a wife for him, his clan chose you. After all, you were kind, soft spoken, has a sweet voice and were gorgeous. Muzan deserved that, or so they said. At that time, he was 13, and you were 12. Soon after seeing eachother, he decided he would indeed marry you. Even if he wouldn't have long to live, it would make him happy to have a perfect wife.

✧

It had been a while year after the marriage, he was now 14, and you were 13. You somehow loved him. Why? He sometimes asked himself. He forced you to marry him. He knocked you up a lot of times, but his sperm wasn't enough to make a child. He knew it caused you a lot of pain. But you never complained. Always stayed with him. Always called him "Muzan-sama" of respect, because he forced you to. You were the perfect wife material. He was the worst husband.

✧

Your state was only, worsening. Even when he started to give you more water because he was feeling guilty, you were only getting thinner. You needed food. That was all. Or so he thought. But in reality? It wasn't your hunger. Getting knocked up every night. Skipping meals daily. No human body could stand that. Only if he knew.

Your body was starting to get slower. And soon, it would stop working completely.

When you two went to the doctors that usually took care of Muzan, the doctor did not seem..happy after checking on you. You were asked to leave. And then, the doctor spoke up to Muzan.

Kibutsuji-sama. Your wife is suffering from an illness.

But the point of it all? Muzan didn't knew. It was.. something normal for him to do to you. Right..?

Idiot. You were still developing. And he thought, starving you would be good.

Death, that was the damn point.

✧

Muzan's whole heart shattered, his world going down after that. But it was the truth. You..were dying. All because of him. Even from his illness, he still had quite some years left. But you? You didn't even have much weeks. While you were waiting outside, unaware of all that, he was inside. He couldn't cry in front of others. Some pathetic doctors. But knowing his wife he loved more than anything would die..he couldn't hold it back. He broke down. While you were all unaware of what was happening in your body.

Since that happened, Muzan took the best care of you. What was the point of knocking you up now? You wouldn't make the nine months of pregnancy anyway. So he stopped. He took care of you. Let you eat. You just thought he was being kind. But oh, no. He was trying to enjoy the last times, days he had with his wife. Before..your body shut down. Since then, Muzan told you. To tell him, even when it was in the middle of the night, when you felt bad. He thought he'd wake up and take care of you in an instant.

Who knew his laziness would win over him knew exactly that situation.

✧

You woke up, sweating. Your chest felt like it was getting squeezed, your heart feeling heavy. Huh? What was this? You were breathing slightly heavily, feeling weird. This never happened before, and the worse of all. You didn't know why. Only Muzan did, yet he was sleeping peacefully next to you. You put a shaky hand on his shoulder, shaking him weakly to wake him up. Muzan, who suddenly got awake, was too sleepy to understand. He just groaned, pushing your hand away and turning his back to you. No, no. Only if he knew. Something was so, so wrong. And you didn't know what. Yet he was still half asleep, not realizing the time you had left was at it's limit. Your breathing was shaky, your pulse only getting slower. This was so wrong. Yet Muzan was too sleepy and didn't notice anything, just keeping his eyes closed, his tone quiet and tired.

..just go back to sleep, {{user}}..

You were dying.
