You hestitated for a few seconds, but decided he couldn't do any harm, so you nodded.

He smiled again. "Thank you. Can I call you (n/n)?

You blushed a bit. "Umm... Okay, that's fine by me" you said. "Do you want to sleep on the couch or in my bed, then I'll take the couch"

"The couch is fine, thank you"

You smiled at him and looked around for a bit. "Where did I put the box with blankets?" you mumbeled to yourself. Then you realised and facepalmed. "On the bed of course"

You walked to the bedroom and took two blankets. You then walked to Sonic and threw them at him. "Here. You can make your own bed up, right?"

"Yeah, I'm fine" he answered

"Okay. Oh, before we go to sleep, a few rules"

"Sure. What are them?"

"One: don't you dare to come into my room unless I tell you you can do it"

"Fair enough"

"Two: no loud noises before 9 o' clock. I need my sleep"

"And what if there's a monster?"

"Then you may kill it, but please do it quietly"

"Sure. Are there more rules?"

"When I'm in the bathroom, you may not come in there, no matter what. Got it?"

"No entering your room, no loud noises before 9 and no entering the bathroom when you're in it. I can live with that"

You smiled at him. "Night, Sonic"

"Night, (n/n)"

You walked to your room and plopped down on the bed, too lazy to change into your pyjamas. In a few seconds, you were fast asleep.

You woke up the next morning around 9:30. You quickly stood up, straightened your clothes and walked to the living room, where Sonic was still laying on the couch. But... something seemed different. He was shivering, but when you came closer, you could almost feel the heat coming off him. Was he sick? You quickly put a bucket next to him, for if he needed to vomit.

You decided to let him sleep, he seemed like he needed it. You quietly walked to one of the boxes and pulled (y/f/b) out, after what you sat down on the chair next to the couch and started reading, looking at Sonic every now and then.

Suddenly, the doorbell rang.

Sonic shot up and looked at the door. "W-who is there?" he asked, shivering.

"I don't know" you answered. "Lay down, you're sick. I'll go check"

He did as you told him and you walked to the door, opening it a bit.

Inside the opening was Genos, holding something in his hands.

"Oh, hi Genos" you said.

"Hi (y/n), can I come in?" he asked.

"Now is not a good time. I'm kind of busy" you answered, looking at Sonic, who looked like he was going to faint.

"What's wrong?" Genos asked. "Can I help you?"

You considered it for a second, but if he saw Sonic in your home, he might start to tease you even more, together with Saitama.

"I... don't think so" you said. "Sorry"

"I know there's someone in there, and it seems like they have a fever. Judging by your reaction, I think it's Sonic" he said.

Your mouth fell open. How did he know that? Oh, right, he could detect heat.

"So it is Sonic" Genos said.

"Yeah, so?" you asked. "Are you going to tease me even more? Are you going to tell my brother?"

"No, I'm not. Really, I can help you"

Suddenly, you heard vomiting. "Fine, come in" you said as you opened the door and walked to the couch. Luckily, Sonic vomited into the bucket, but not everything landed in it. There was still something on him and the ground.

Genos came in behind you as you took a towel and started cleaning the floor.

Sonic grunted. "I hate being sick. And what's he doing in here?" he asked you.

"He's going to help me take care of you. Can you stand?"

"Y-yeah, why?"

"Then you can take a quick bath. I don't want you to be dirty" you said as you felt his forehead. Yep, he definitly had a fever.

"But... I don't want you to see me naked..." he mumbeled. How could he think about that when he was sick?

"Is it okay if Genos washes you then?" you asked.

Sonic grunted, but realised there was no other choice. "Fine..."

"Hey! I don't want that" Genos said.

"You agreed to help me" you told him. "Well, this is helping"

He sighed. "Fine..." He then helped Sonic stand up. "Can you walk by yourself?" he asked.

"Yes" Sonic said, but after two steps, he fell over.

"Definitely not" Genos said as he caught the black-haired boy. (No, there isn't going to be any Genos x Sonic-chan, don't freak out. This is Sonic-chan x reader-chan, okay?)

"I'll go ask Saitama if he has some pyjamas to borrow" you said. "Don't kill eachother, please"

"Yes, (y/n)" both of them said as you walked out, to your brother's house. "Hey, Saitama, are you home?" you asked, knocking on the door.
