You and Monoma had been engaging in your usual banter during class, throwing witty remarks back and forth while the rest of the class laughed. Monoma, being his usual over-the-top self, threw in some playful comments about how "Class 1-B had the superior talent, and it was obvious you belonged with them."
Bakugou, seated a few rows away in the shared class session, gritted his teeth. He didn't like how close you were with Monoma, especially when the latter always managed to get under his skin. He could feel his irritation rising every time you laughed at Monoma's jokes.
As class ended, you high-fived Monoma before heading out with Kirishima and Bakugou. Bakugou stomps, muttering under his breath, "Tch, that guy's so damn annoying."
You caught the tail end of his complaint, chuckling to yourself. "Kat'ski, you're always so serious."
He didn't respond, but the glare he shot Monoma's way was enough to make the Class 1-B student raise an eyebrow in amusement.
▬▬▬
You and Monoma had decided to study together in the library for the upcoming quiz in Present Mic's class. The two of you sat at a quiet corner, huddled over a set of notes, occasionally whispering and giggling about something Monoma had said.
Bakugou walked into the library, looking for you, only to spot you with Monoma. Again. He narrowed his eyes, hands twitching with the urge to march over and yank you away from him.
As he watched, Monoma leaned a little closer, pointing something out in your notes. Bakugou's fists clenched at the sight, the idea of Monoma being anywhere near you making his blood boil. He stormed out of the library before he could cause a scene.
When you found him later, Bakugou didn't mention it, but you noticed how unusually quiet and tense he was for the rest of the day.
▬▬▬
You and Monoma had run into each other in the cafeteria, and naturally, he insisted on sitting with you. You didn't mind, and the two of you were deep in conversation when Bakugou entered, tray in hand.
His eyes immediately found you, and the sight of you laughing at something Monoma had said made his face twist in anger. Bakugou stomped over to the table, dropping his tray with a loud thud.
"What's so funny?" he barked, glaring at Monoma.
You looked up, surprised by his sudden appearance. "Oh, hey, Kat'ski. Monoma was just telling me about-"
"I don't care what he was telling you," Bakugou cut in, shooting a death glare at Monoma. "You're done eating with him. Let's go."
Before you could respond, Bakugou picked up your tray and marched away, expecting you to follow. Monoma just smirked as he watched Bakugou's jealous fit, giving you a knowing look before you hurried after your fuming boyfriend.
▬▬▬
It was during one of Class 1-B's team-building exercises when you and Monoma had been paired up. The two of you worked well together, as always, and Monoma made a big show of being your "ultimate partner," much to the amusement of everyone around.
Bakugou had been watching from a distance from his class, who had the same team-building exercises as Class 1-B. The sight of you and Monoma once again joking and working together setting him on edge. His patience had been wearing thin with each encounter, and now, he'd reached his limit.
As Monoma threw an arm around you, making a joke about how you two made the perfect team, Bakugou snapped. Without warning, he stormed over and grabbed your wrist, pulling you away from Monoma.
"Oi, what the hell, Bakugou-" Monoma started, but Bakugou ignored him, dragging you toward the nearest empty classroom.
Once inside, he slammed the door shut, his eyes blazing with jealousy. "I'm sick of seeing you with that bastard," he growled, his grip on your wrist still firm but not painful.
You stared at him, your pulse quickening. "Kat'ski, what are you talking about? Monoma's just my friend-"
"I don't care!" he snapped, stepping closer, his voice rough with frustration. "He's always all over you. Every time I see you two together, he's got his arm around you, or he's cracking some joke, and you just-" He ran a hand through his spiky hair, clearly agitated. "You laugh at everything he says. It pisses me off."
You frowned, tugging your wrist from his grasp, but not stepping away. "Kat'ski, I laugh because he's funny sometimes. But that's it. He's just a friend."
"Just a friend?" Bakugou scoffed, his eyes narrowing. "He doesn't act like he's just a friend. You're too close."
"Close? We're just joking around!" You crossed your arms, trying to understand why Bakugou was reacting like this. "Why are you so worked up about this? You know I don't like Monoma that way."
Bakugou's jaw clenched as he struggled to find the right words. "I hate the way he looks at you," he finally muttered, his voice dropping in volume but still tense. "Like he thinks he's got a shot or something. It makes me wanna blow him up."
You softened, realizing just how deep his jealousy ran. "Kat'ski," you sighed, stepping closer to him, "you've got nothing to worry about. You're the only one I care about."
He avoided your eyes for a moment, his fists still clenched by his sides. "Tch... I know that. But it's not just about you. It's about him, too."
You placed a hand on his chest, feeling the tension in his muscles. "I promise I'll set boundaries with Monoma if that's what you want. But you don't need to feel threatened by him, okay? You're the one I'm with."
Bakugou's eyes flickered with a mix of stubbornness and vulnerability. "It's not about feeling threatened. I just... I don't like sharing you like that."
A small smile tugged at your lips as you leaned up, brushing your hand against his cheek. "You don't have to share me with anyone. I'm yours, Kat'ski."
His expression softened, though he still looked slightly irritated. "Yeah, you better be," he muttered, pulling you closer by your waist. "Just... don't let that idiot get too close again."
You smiled, resting your head against his chest. "Deal."
He let out a sigh, wrapping his arms around you, and for a moment, the tension between you melted away. "Good," he grumbled, pressing his chin to the top of your head. "'Cause I'm not letting anyone else have you."
