Bakugou X Kirishima's sister (Reader)

Extra Chapter 2

Here is the last special chapter for Valentine's Day while I figure out how to wrap everything up. The first short story is from your third year in high school and the second is set a few years after graduation. I hope you guys like them! ❤️

It was the start of your third and final year of high school, your class was overly excited to start the beginning of the end of your time at UA. Katsuki walked with you to class, his hand freely intertwined with yours. It was nice to be able to show off to everyone that the two of you were a couple. You walked with him to his desk, telling him some funny story about what you and Eijiro had done over the break. You stopped suddenly, something on his desk caught your eye.

"Hey, dumbass, are you going to finish what you were saying?" Katsuki waved his hand in your face, pulling your attention back to him.

You ignored his question, moving to pick up an envelope with his name on it. Turning it in your hand you looked over at him, "What's this?"

He stared at you with a raised brow, "Hell if I know."

"Can I open it?" You questioned, flipping it in your hands.

He waved his hand at you, "Go for it."

You tore it open, already having an idea of what it would be, but you were curious to know who would have the confidence to send your boyfriend a confession letter. You glanced through the letter quickly, only to find that you had been right. Some girl, who's name you didn't recognize, had tried to confess her feelings. Writing something along the lines of how she had appreciated his help when she had fallen in the hall and how she thought he was an amazing student and blah blah blah. You glanced up at Katsuki over the paper.

"What?" he questioned, when you didn't say anything.

"Getting other girls to fall for you, Katsuki?" You put the letter down on his desk.

He rolled his eyes at you before a smirk spread across his face, "Is someone jealous?"

"I- No." you said a bit too quickly.

His smirk only grew wider, more smug, "You are jealous. But can you blame them babe? Who wouldn't want to be with the best student UA has ever had?"  He paused, taking in your glare, "How the tables have turned."

You crossed your arms, already tired of his smug attitude, "What are you talking about?"

"Do you know how many guys I've had to deal with, that have tried to take you from me? Not that they could. Yet here you are, complaining after just one person."

His smile remained unwavering as you rolled your eyes, shaking your head. "I am not jealous," you spoke before turning to head to your desk.

You shoved your conversation to the back of your head, instead trying to focus on what your teachers were saying. How dare he insinuate that you were jealous. That wasn't what you were feeling at all. Or so you told yourself. By the time lunch came around you sat at your normal table, right between Mina and Jirou, both of them interested in what was on Katsuki's desk this morning.

"It was probably just some first year that didn't know any better. I mean Bakugou has calmed down some since the two of you have gotten together. So, she probably just doesn't know how intolerable he really is." Jirou spoke before she popped a fry into her mouth, chewing thoughtfully as they both came up with excuses for the girl who had made the mistake of confessing to your boyfriend.

"Plus, the school year just started, and it's not like you and Bakugou really hang out at school. You guys don't even eat lunch together, so she probably just didn't know." Mina added, trying to help the situation.
