She's mine and only mine | Yandere Bakugo X reader

Summer

I woke up to a knock on my door. I didn't change out of my clothes from the day before. I was still wearing Katsuki's hoodie. Half asleep I got up to answer it. It was probably the mailman dropping off a package.

I opened the door so see Katsuki. Shit. I still had his hoodie on.. His face was red when he saw I was still wearing it.

"Oh hey! Sorry! I just woke up! What time is it?"
"10:30.."
"Dammit my alarm didn't wake me up.."

Katsuki chuckled.

"Here. Come inside, I'll get ready an we can get going to the GYM. If you're hungry help yourself to anything in the kitchen."

Katsuki came inside. He had 2 water bottles in his hands, one was mine and the other was his. I went to my room an Katsuki did something.

I took off Katsuki's hoodie, neatly folded it, and placed it on my bed. I changed into a different pair of black leggings and just put on a yellow cropped top. Grabbed my phone and wallet. I brushed my hair, threw on some sneakers-

"AHHHH!" It was my mom.
She must've just got out of bed sense she got home late.

I ran out and saw her holding a knife in the dinning room.

"Woah lady! Put the knife down!"
"Who the hell are you?! How did you get into my home?!"

I ran in front of Katsuki.
"Mom! Everything's okay! He's a friend! We're gonna go to the GYM! He was waiting for me to finish getting ready!"
She put the knife down.
"Oh...Well I'm sorry young man! I thought you were an intruder!"
"It's cool."
"So.. {y/n}?"
"Yeah?"
"Who's this?"
"Oh right! Mom this is my classmate Katsuki Bakugo. Katsuki this is my mom."

The two introduced themselves.

"Oh wait! {y/n}!" Katsuki said.
"Yeah?"
"You said you had just woken up so I made you an omelette. I didn't want you to get dizzy when we go to the GYM. Also I filled up our water bottles." Katsuki said pointing at the omelette at the table.
"Oh thank you! I thought something smelt good."
"I ate before I got here so I just made some for you."
"Thank you!" I said with a smile.
He smiled at me.
Mom and Katsuki got along fairly well. As I ate the omelette, which was really good by the way, mom and Katsuki were talking.
"Oh {y/n}, I'm gonna be working late at the hospital again."
"Again! But you have for the last 2 weeks already!"
"I know sweetheart but there are lots of villain attacks lately. And speaking of villain attacks..." Crap she heard about the villain attack... "Aren't you the one who defended himself from that sludge villain?"
"Yeah..." Katsuki replied.
"I was shocked to hear that {y/n} and Izuku saved you."
Katsuki stayed quite at her comment.
I finished eating and washed my plate.

"Ready?" Katsuki asked.
"Yup!"

"Bye you two! Stay safe.
"Bye mom."
"Later."

And we headed to the GYM. Showed them our memberships and went inside. We walked over to the ellipticals and a guy, about our age, made a comment about me to his friend.
"Damn! That chick in yellow has a nice ass bod!"
"Hell yeah she does!"
"I'd smash that any day!"
"Oh meet too."

Then one shouted at me.

"Hey! Leave your boyfriend and be with me instead! I'll treat you better than he ever could!"

Cat-callers... These are always annoying.. I just decided to keep walking.

Katsuki grabbed my wrist and stopped walking. He had a tight grip on me, it was starting to hurt. He turned around.
