This is not romantic, just some sweet stuff between these two.
In this one-shot Kevin is 8, and Fritz is 17.

Kevin was abandoned by his parents and after the murders (death of his older sister Amy), he was all alone. Fritz lost his cousin Fredrick, and found Kevin in the pizzaria. Fritz took Kevin in and is taking care of Kevin.

*Fritz POV*
It was late in the evening. I was still downstairs, but was prepairing myself to go to bed. At least that's what I was doing, until I heard Kevin running down the stairs.

"Kevin, what's wrong?" I asked.
He ran towards me, jumped onto my lap and hugged me tight.
I hugged him back and started to rub circels on his back.
"I had an nightmare" he said between sobs.

"You and Erik left me, but I didn't know what I had done wrong" Kevin said and started crying again.

"I would never leave you, nor would Erik leave you"
"But it felt so real"
"But luckily it wasn't, I'm still here for you and I'll always be there for you"
" *Snif* Thanks Fritz" he said, giving me a hug.
"No problem. Are you calm enough again to go back to bed?"
Kevin knodded as an awnser. He was trying to wipe away his tears.

He walked out of the livingroom, when there was lightning. He ran back to me as fast as he could and jumped onto my lap. He was shaking with fear.
"Calm down, I'm here, nothing can harm you"

Then there was another lightning, almost insantly followed by the thunder.
'that one was very nearby'
"I know that you don't like thunder, but I kinda wanted to go upstairs. You can sleep with me tonight if you want"

"Yes please" Kevin said, who had let go of me and was holding onto his Chica plushie. Kevin walked before me when we walked up the stairs. He walked into my room and sat on the bed.
I grabbed my stuff to sleep in, and walked into another room.

"I'm going to change, alright"
"Why are you going to change in another room? Did I do something wrong?"
" *Sight* No, you did nothing wrong Kevin"
"Is it because of you weight? Because I don't think that there's anything wrong with it"
I laughed a little bit, and walked towards Kevin.
"Thank you for saying that" I said while ruffling his hair.

I had thought that the storm had calmed down, but I turned out to be wrong.
Because another lightningbolt had struck nearby.
Kevin was hiding under the covers.

I quickly changed and layed down next to Kevin.
Unfortunatly, another lightningbolt struck and this was the last straw for Kevin.
He had just calmed down, but now he was shaking again.

"Hey Kevin, my mom used to sing me a lulaby whenever I wasn't feeling to well. Shall I sing it to you"
I felt Kevin nod, he was stil completly covered by the blanket.
He lifted the blanket a little bit, so he sould see me.

"Soft kitty, warm kitty, little bals of fur, sleepy kitty, happy kitty, pur, pur, pur"
Kevin smiled a bit.
"What is it Kevin?" I asked.
"Amy used to sing this to me. She taught me the lyrics"
"Do you want to sing it?"
Kevin nodded violently.
"Go on, I want to hear you sing it"

"Soft kitty, warm kitty, little bals of fur, sleepy kitty, happy kitty, pur, pur, pur"
When he was finished, I was silent because of his voice. He had an amazing singing voice.
"Was it good?" Kevin asked, tilting his head a bit.
"No, it was amazing. You have an amazing singing voice" I said, giving Kevin a hug.

" *yawn* Thanks" Kevin said sleepy, hugging me back.
"Go to sleep, I'll be here when you wake up" I said, planting a kiss on his forehead.
Kevin shifted a bit, before finally falling asleep.
A couple of minutes later, I was sound asleep as well.
