(A/N: please let me know what you guys think of the story in the comments. Remember, I'm still taking request for my Shouto one shot book.)

It's been a few days and I have officially moved into the Bakugou household. I like living here, except for the fact that Katsuki still hasn't talk to me. Every time he would come back to school and I was on the couch watching TV, he wouldn't even look at me and head to his room. Does he even know I live here now?

I stood at Katsuki's bedroom door. Damn it, I'm bad at this, it's been years. What if he doesn't recognize me? Pull yourself together (Y/N), I slowly knocked.

"Go away hag." Katsuki immediately responded.

"No Katsuki, it's not your mom. It's me, (Y/N)?" I said back. The door unlocked and opened slowly, Katsuki's red eyes looked like they were glowing.

He rose his eyebrow. "What do you want?"

"I just wanted to let you know that I live here no-"

"I know you live here," Katsuki cuts me off, "now go away." He then closed the door, but I was able to hold the door open.

"There's more," I got his interest, "your mom told me that you want to get into U.A., I want to get in just as much as you do. So, I have a favor to ask you." I choked out, I was trying to avert my eyes.

I fell onto my knees, my palms on the floor. Katsuki was obviously confused. But I needed him for this, he's the only one I know can do this for me.

"Please Katsuki, train me." I softly said. I look up. I wasn't sure if Katsuki frowning and his downward eyebrows were his neutral face.

"Fine." I gasped.

"Really?" I stood up.

"On one condition," he didn't stop, "if you get accepted into U.A., I have to have you do me a favor. Got it?" Katsuki got up in my face, I'm getting chills just from his hot breath hitting my face. I agreed and held out my pinky.

"Pinky promise?" I said with a childish voice. He didn't say a word, he only link his pinky with mine.

(The next day)

Katsuki told me my training schedule: after school I would meet him at his training place, which is the coast of a beach I went to when I was small.

I jogged all the way there. Since the key thing I wanted to work on was how to control my flash bang quirk, I wore a hoodie, sports bra, and basketball pants. As I made it to the coast, I see Katsuki sitting on a rock, stretching. Seeing him stretch made me a little flustered, he was wearing a tank top so his arms were exposed, he was quite muscular.

"Hey, Katsuki." I shouted out. He flinched and looked down at me, seeing me waving my arms around like an idiot. He jumped off of his rock and faced me, his face immediately going pink.

"Why are you just wearing a bra?" He asked, turning the other way.

"Since my quirk is flash bang, a brighter light will flash with more exposed skin," I explained, "I was hoping to control it so that I don't to rub moisturizer all the time."

Katsuki looked back, trying not to look down at my chest. "Alright then," he said, "since you want to approve that stupid quirk, I want you to activate it now."

I nodded, taking off the hoodie and readying myself. A flash of light erupted out of my body and out to the outside world, Katsuki covering his eyes.

The flash disappeared and I already felt the urge to scratch myself. I brought a bag with three moisturizing bottles just for the occasion. But Katsuki grabbing my wrist stopped me.

"You need to control your urge," he explained, "even if your skin starts itching and it's dry, keep going."

Wow...is Katsuki saying something smart? Even if it is smart, it's still way to much for me. But, I had to follow his orders, which means actually taking his advice.

For the entire day, my skin felt like stone, my eyes wanting to close. Katsuki was breaking my limit and that's not a good thing. And guess what, all he did was either follow me if he told me to run, or just sit on his rock and yell at me. You're doing a great job Katsuki.

The sun was setting and I was cover in sweat and tears. "You still gotta long ways to go." Katsuki yelled at me. Before I could respond to him with a comeback, I fell to the ground and blacked out.

Katsuki's Third P.O.V.
He saw her faint. Katsuki jumped off of his rock, walking towards her unconscious body, cracked and tired. While walking to her body, he also grabbed her bag of moisturizer bottles, opening one and rubbing the moisturizer on her body. 

When she was finally covered, Katsuki put the bag over his shoulder and picked up (Y/N)'s body bridal style, taking him and her body back home.

When he got to the front door of his house, he was able to open the door and also able to open the door to (Y/N)'s new room, laying her body softly down on her bed.

"For the rest of the months to come, we'll be training everyday after school until the entrance exam. And I'll train with you to make it fair." Katsuki said softly. He turned off the lights and slowly closed the door.

(A/N: I'll let you guys know that I'll hopefully will be seeing Two Heros tomorrow with my friend and I'll let you know what I think about it. Because of that and being part of a youth theater, I won't be posting a new chapter until maybe Monday of Tuesday.)
