A time skip to August of next year. Kayoko is 2 and you and Katsuki are 26.
It was hot when you woke up, and Katsuki wasn't there. Which was strange since he didn't have work today and you didn't hear Kayoko up. But you did hear the sound of vomiting when you sat up. You looked over at the bathroom to see the door open. After giving a quick stretch you got up and walked to the bathroom. Katsuki was there, hunched over the toilet throwing up.
You walked over to him, sitting down and rubbing his back while he kept going. Once he was done he sat up and wiped his mouth then flushed the toilet. He looked over at you, and that's when you got a look at him. "Jesus you're sick." "I'm not sick." You gave him a look before feeling his forehead. "Katsuki you're hotter than hell, go back to bed." He grumbled at you, then sneezed right after.
Sighing, you pulled him up and put him back to bed. "I don't need you to take care of me y/n." "Hun, you're paler than pale, your eyes are red and puffy, you can't breathe through your nose, and you're burning up. I know you're not going to like it, but I'm going to take care of you until you're better." You walked to your drawer and pulled out clothes, then went to take a quick shower. When you came back Katsuki was passed out.
"Of course..." You softly chuckled and quietly made it out of the room and walked over to Kayoko's. She was up, watching cartoons and laughing at them. "Morning Peanut." She looked over at you and smiled, getting up and climbing out of her crib. Yeah, it was time for a big girl bed. "Hi, mommy!" She ran over and you picked her up.
"Guess what baby?" "What mommy?" "You're going to grandma and grandpa's." "Yay!" She smiled and clapped while you picked out an outfit for her. You needed to get her there and get back so you could take care of Katsuki. Once Kayoko was dressed and ready you couldn't help but aww. "Can mommy take your picture baby?" You took your phone out and Kayoko gave a smile at the camera. Even if she wasn't looking at it.

"We need to learn how to look at the camera when you can't see yourself, ma'am." She just smiled at you while reaching to be picked up. You did as she wanted, and in return, Kayoko kissed you. "Aww thank you, baby." You smiled at her before grabbing her bag and going out to the car.
You were able to drop Kayoko off in record time, and Mitsuki and Masaru were more than happy to spend time with their granddaughter for a couple of days. You did make a quick stop at the store to get some medicine and soup, but you did make it back home in 10 minutes tops. When you came back Katsuki was awake, just laying in bed groaning.
"I see you're not feeling any better." He turned around to look at you then pulled the covers over his head. "Aww c'mon you big baby, I got you some soup and medicine." He still didn't move, so you threw the covers off of him and dragged him into the kitchen. "I don't want it," Katsuki said as you held the plastic cup of medicine in front of him. "Katsuki, take the damn medicine." He still wouldn't take it, so you pulled his hair. He opened his mouth to start yelling but you poured the medicine into his mouth before he could start.
Katsuki swallowed it, then softly punched your thigh. "That's for drugging me, women." He said as he put his head down on the table. "Yeah yeah whatever, I'm gonna make soup now. You want chicken soup or normal?" "Chicken please." You kissed his forehead before going to make the soup. This was going to be a long couple of days.

It had been three days, and Katsuki had got better. Which you hated because you had got worse. You'd caught whatever he had, so now he was taking care of you. Oh, how the tables had turned. "Hey, baby," Katsuki said as he sat the cup of water on the nightstand. "Hey, the asshole who got me sick." "Yeah... That's me." Katsuki smiled before handing you two pills to take.
"I think you're getting better. Still vomiting, but your fevers went down a bit and you can sort of breathe through your nose again." He felt your forehead, and you weren't as warm as before. "You're still warm, but not "hot as hell", not in this sense of course." You hit him with a pillow after that comment, Katsuki just laughing at you. "I'd totally fuck you right now if you weren't sick." "You'd fuck me if I was." "...You're right. I would, and I am." You let out a nasally laugh as Katsuki threw the covers off of you and pulled you in for a kiss.
Now you'd have to try and not sneeze on him as you had sex.
