Katsuki's New Sibling Life (boku no hero academia x child reader)

Scenario Batch #1

Hey and here is the Scenario chapter I had promised you about. I am so sorry it took so long ;-;

I will also used this to finish up the requests that had been waiting for SOOO long.

When Reader got sick

Katsuki stared at your with an 'I told you so' look as you sneezed and coughed in bed.

Seeing that look you lightly glared barring teeth a little bit as habit.

"Yeah yeah, I know, Even with a quirk I can still get the flu... How was I supposed to know I was allergic to pollen!?" You argued.

Katsuki rolled his eyes and left the room but before he could he felt your tail wrap around his wrist stopping him.

"C-Can you please stay?"

You asked but Katsuki grumbled saying he'll get sick too, if he stayed.

With a sad look you dropped your hold and looked down on your lap with a lonely look.

Seeing as you won't argue anymore he left your room slowly closing the door. Doing so he looked at you for a few seconds before leaving it slightly ajar so it won't be so hot.

'Why the fuck did they have to get the when the hag and old man are gone..' He thought grumpily.

Roughly sitting down he turned on the Tv.

"Big brother..." the child in the Tv weakly say as he coughs. "You didn't have to look after me.."

"Don't be an stupid, of course I would look after you, I am not a jerk like other brothers —" Katsuki shut the Tv off and stomped around grumbling.

In your room you sighed sadly feeling as if the walls were closing in, sure the air-conditioning is on, and you nearly wrapped in a blanket you still felt a bit heavy in the heart.

Suddenly the door was kicked open. You blinded in surprise as your brother with a mask over his nose and mouth stomped to your bed.

He moved you over and sat on the bed himself, and placed your head on his chest as he pulled a blanket over your shoulder.

You were bewildered, this wasn't on the instruction box, when you got your brother that he would sometimes do a full 180 degree on his personality.

"Katsuki?—"

"I AM NOT A JERK! I AM A HERO!" He yelled. You looked at him in question before shrugging off and snuggling closer to him.

"Don't say a fucking thing of what has happened."

"Sure thing..."

When Katsuki gets sick

"You are sick..."

"I am fine!" Katsuki yelled in anger as he head felt like it was brining and he was sweating so much he wasn't aloud to touch anything.

Small explosion were all present in his palms.

He was also forced to lay down outside so that he won't start on the fire alarm.
