Muzan was sick from the womb. Which meant he was sick inside your stomach and when you gave birth he was still sick which you had to take care of him as a mother of course. It was your job to protect and heal your son. Your husband didn't buy into the idea of having a sick son who was probably going to be sick the rest of his life and one who couldn't even have children. Your husband wanted to abort Muzan when you found out you were having him while he was sick in your stomach, but you refused. You didn't want to kill your baby boy when he was just sick in your stomach he couldn't help it.

After a few days, you sort of recovered from birth, and were at home with your son while your husband was out messing with other women he so-called 'worked' with. You knew he was cheating, but you didn't care because your main focus was your son who needed you, and needed you to love, and take care of. Muzan was crawling on the floor with his eyes shut. Of course, he was going to do that but you also had to be careful of what he was doing because you didn't want him to get hurt, or even worse, killed. You were gonna pick up Muzan, but Muzan had let out a whine at you, despite his eyes being shut and unaware of his surroundings.
