The next morning
Y/N POV

I woke up in a little pain. 'Ugh he went to hard'. I thought as I got up and got dressed after I realized he was still asleep so I went over to him and bit his ear. He yelped in pain as he jumped outta bed getting ready.
"Ready for class?" I asked him while he was in the shower.
"Yeah will you be able to walk without showing signs of pain?" He responds. I walk in the bathroom and brush my teeth and said "yeah" we get to class and I got scolded be midnight and Aizawa about driving the bus with out a teacher. I retaliated badly and yelled at them saying it was either that or fighting the league of villains again.

Bakugo came from behind me at lunch and reached his arms around my waist.
"Hey y/n thanks for saving all our asses out there and your uniform looks a little short!" Mineta said with a bloody nose. I got down to his short level as I'm as tall as katsuki and punched that little twerp in the face and looked at sero, and Denki with disgust.

We got back to class and Mr Aizawa told us that if a villain were to attack again not to run or fight but to get help from the pros until we are pros. After the class got back to the dorms I hoped in the shower with Katsuki.
I was thinking leaning against the wall of the shower when Katsuki asked something.
"Where did that burn come from?"
"Huh? Oh that umm well you where a bit viscous last night and you also bruised me up pretty badly but nothing I can't handle." I answered. He looked at me with sad eyes I hated to see him like that. I decided to finish rinsing my hair but when the water hit the burn it felt like razor blades and I almost fell if not for Katsuki and the handle of the shower.
"Are you ok?!" He asked
"Baby, I'm fine just the pressure of the water was shocking." I said reassuring him. I got out and wrapped my shoulder and down my back in bandages. And got dressed and headed to the common room to wait and talk to the others. When Katsuki got down from his room I sat in between his legs leaning against his chest as the other started to walk into the room. When shoto showed up he looked at me with apologetic eyes and momo walked over to him and kissed him after that I went to katsukis room and slammed the door shut.

Katsuki POV

I finished getting dressed and went to the common room. While y/n was sitting in between my legs she had her head on my chest. The others started to come in and when half n half walked in he looked upset then momo kissed him and y/n walked out of the room pissed and slammed the door of my room.

~~~flashback two years ago~~

Y/n POV

It was shoto and I's 1 year anniversary and I was walking to his dorm and heard moans coming from it. I tried to open the door but it was locked so I called Bakugo to help me. When he opened it I was so pissed at what I saw.
"Y y/n" shoto said "it's not what it looks like!" He stated.
"Oh good so my boyfriend is not in his bed doing it with my cousin." I said sarcastically.
"N/n" momo said.
"STOP...FUCK BOTH OF YOU IM DONE!" I coldly yelled at them and ran to Bakugo and hugged him balling me eyes out.

~~~~~~end of flashback~~~~~~

"Babe open the door please." Bakugo said politely.
"Just come in*hic*." I said while crying. He opens the door and sees me on the floor with my gloves off and wearing my spandex. It revealed a lot of scars and cuts. Then he noticed the pocket knife in my right hand.

"B-babe?!" He said terrified at the site he was seeing and rushed to her side and took the knife and stuck it in the wall.
"I'm sorry." I said while crying and bleeding. After about ten minutes he cleaned up your wounds and laid you in bed where you passed out.
