(A/N: I want to clarify that this story is following the anime and the reader is coming to the Bakugou household at the same time as the slime monster incident.) 

"I'm so glad that you want to live with us (Y/N)!" Mitsuki greeted me at the front door of the Bakugou household. She went in for a hug immediately, almost choking me. "You didn't skip school just so we can talk, did you?"

"No Mitsuki," I clarified, "my middle school lets us out an hour earlier than Katsuki's." I went to a all girls school while Bakugou went to a all boys school. we were in grade school together, but my parents, brother and I moved to an apartment that was close to the middle school I was going to attend.

"Well then, come in. I'll prepare you some juice and crackers, wait in the living room, OK?" I nodded, walking into the living room and plopping onto the couch, as Mitsuki went into the kitchen.

While Mitsuki was doing that, I got off the couch and walked to a wall full of framed pictures of Bakugou back in kindergarten. But there were also pictures of me with Bakugou and the rest of his friends, standing on a big rock with are fists in the air.

Back in kindergarten, Bakugou allowed me to be part of his 'hero agency'. As expected, the two boys that were part of it made fun of me because I was a girl. But, for some reason, Katsuki defended me, and made me co-leader of the agency. There was also Izuku, he was too nice to me, he was so sweet and kind to me it mad me blush. I could remember vividly about all the stuff we did:

We were at the playground, Katsuki giving a speech about how awesome All Might is. He's so cool, both Katsuki and All Might.

"Hey Bakugou, why do we have a girl in the agency? She's a girl, she'll just slow us down." One of the boys asked. I gasped, girls can be just as cool as boys.

"She's here because my mom made me drag her here. But I'll kick your butt if you say anything bad about her. Understand?" Bakugou got all up in the boy's grill. I smiled at his heroic action to save me.

"(Y/N)?" a familiar voice echoed through my ear, I turn around and see Leo-

I gasped, grasping my shirt, my heartbeat rising. I stumbled a bit and almost fell on the coffee table.

"(Y/N), are you OK? I heard you gasp." Mitsuki came out of the kitchen, hold a tray of crackers and two glasses of juice. 

I was on the floor, trying to catch my breath. I got back on my feet and nodded. "I'm OK Mitsuki, I just tripped on my foot. I've always been a klutz, huh?" I jokingly said, trying to laugh it off. 

Mitsuki and I sat down on the couch and started talking. We talked about the usual moving stuff and talked about how my life was after the accident, Mitsuki trying not to say my brother's name. Trying to relax, I leaned down on the couch. but suddenly, my elbow hit the TV remote and the TV turned on. I immediately apologize, but I froze when I saw what was on the TV.

It was a news report about a slime monster attacking a high school boy, that boy being Katsuki Bakugou. It's been a while but I knew Katsuki when I see him, his spiky blond hair, his red eyes, and his aggressive actions, all of them were the Katsuki I knew. 

I looked to my side, seeing Mitsuki gasp, she grabbed her phone and called her husband. I, on the other hand, was shaking, seeing one of my only friends I made beside Izuku struggle and almost die, it made me gag and sick to my stomach.

After Mitsuki's phone call ended and the news changing to another story, the door opened so suddenly that we both jolted, looking to see an old face.

"Care to explain the slime incident Katuski?" Mitsuki got off her seat, standing face-to-face with Katsuki.

"I don't have time hag, I'm going to bed early." After hearing Katsuki's voice, he was much more gruff and rude, even calling his mom a hag. He only turned to his room, not even batting an eye at me, and slammed the door shut.

We were silent, not even moving, a little shock. Mitsuki sighed. "I'll fix you up dinner and you can sleep in our guest room."

I only nodded when she walked back to the kitchen. I looked at Katsuki's bedroom door, I have no confidence to talk to him now, but soon, I'll try my damn hardest to get Katsuki to like me again. Like old times.

(A/N: I hope you guys like it. I have an idea, I'll write Shouto Todoroki oneshots on my phone, and I'll write this book on my school computer. It also seems that gifs only work when I download them on my computer. Anyway, thank you for reading and I'll see you soon.)
