Ever since you were 5 years old you were neighbors with Katsuki. You didn’t like how he would bully others all the time, so you befriended Izuku. And just like that you both became rivals. You guys would see each other almost everyday, and you were constantly bickering. For some reason he still seemed to refuse to leave your side though. Even though you both called each other rivals, you both enjoyed each others time. You both often hung out and trained together. Your arguments were never serious. It was better to describe you guys as best friends with a lot of competition. You both are now in class 1A. You were on par with him strength and smarts wise.
Growing up you’ve always been a bit of a perfectionist, but ever since you’ve joined UA it’s worsened. You were in the hero course, in class 1A. You worked all the time, you didn’t give yourself a break really. Your friends and teachers have been telling you that you needed to take a break, stop being so hard on yourself. But you just said you were fine. Katsuki was definitely starting to get sick of it. He understood wanting to be the best and wanting to help as many people as possible, but he didn’t like seeing you tired and stressed so much.
Thats kinda how you got in your current situation. You had been working all day, classes, studying, and training. You got back to the dorms at 9pm. You were exhausted, looking forward to sleeping, but instead you were met with Katsuki. He immediately started berating you on how you work too much and stuff and he forced you to go shower. When you came out he made you eat some food he made for you. Now you were lying on your bed, your dorm room dark.. except Katsuki was laying with you, he was holding you in a firm grip, holding you against him. “I’m only doing this because I don’t trust you to not get up in the middle of the night and start studying or something like a fucking nerd.” He said, seeming more flustered than you. He was basically cuddling with you after all.
