a/n: omg hell yessss I made it a little angsty but I hope he’s not too OOC
You narrow your eyes at the blonde sitting right in front of you. His eyes narrowed and his lips pulled into a deep frown that you’ve never seen before. Clenched fists that are slightly shaking, he glares down at the floor with such an intensity that almost frightens you. Almost.
He’s been that way for the past half an hour, with no warnings at all. It’s weird, how this morning he wasn’t giving two fucks about anyone or anything at all, and now he’s just… furious isn’t even the word to describe it. Neither is rage. This is something else, and you knew it.
“Kats, just spit it out already.”
You’ve been trying to coax an explanation out of him for the past twenty-seven minutes, and yes, you’ve been counting. He’s never hid his anger from you. Or anyone, actually. But definitely not you.
“Kats, I swear to god, if you don’t start saying anything then I’ll go back to my conversation with Midoriya—”
“Get that bastard’s name out of your mouth.”
It was a quick mumble. A short demand. A command, if you will. He’s never said shit about Midoriya with such pure hatred that it did confuse you, and you started to question if you really understood Katsuki in the first place.
His brow furrowed and his teeth gritted, his glare shifts from the floor to your shoulder, avoiding your direct gaze. He couldn’t bring himself to glare at you, no. The last thing that he wanted to do was to direct his anger at you. You were one of the most precious people in his life, and he wasn’t gonna risk anything, much less even glaring, to fuck it up. But looking down and glaring at the floor looked utterly pathetic, too. So his eyes dart from the wall behind you, to your shoulder and neck, but never your face. You didn’t deserve that. It wasn’t your fault, either.
He knew it’s not your fault, so why did it sting so much to hear you laughing with that bastard? He didn’t get it.
“Never mind. ‘M fine. It’s nothing.”
“Kats, you can’t be mad like that and not explain yourself.”
It’s true. He knew that he owed you an explanation, and a good one. Shame crept up on him as he realised that he snapped at you. That you were on the receiving end of his anger. The promise he made to himself— to never, ever make you upset, or to ever let you feel like the reason that he’s mad— was now broken in his eyes.
“I’m… sorry. For snapping at you. It’s not your fault,” he mumbled under his breath.
It wasn’t snapping, but he hated the fact that he still could have upset you.
“Kats, it’s okay. I’m fine, I promise. What’s wrong? You know you can tell me anything that’s on your mind, right?”
“No, it’s nothing,” he mumbled, though it’s clear that his snapping only made him more irritated with himself.
“It’s not nothing if you’re…” you trail off, not wanting to point out the current tears in his eyes.
“Huh? I’m what?” Still oblivious to the tears, he looked around and found nothing.
“Kats, seriously. Tell me, now.”
The firm gaze directed at him from your eyes made him freeze, and the gentle tone in your voice made him hesitate. He was surprised, to say the least, that you were still here, trying to help him while he stood there in front of you like an idiot. If you left now, he wouldn’t have been surprised. In fact, he understood why you would do that, and he couldn’t blame you. This emotional, vulnerable part of him finally showed for the first time in your relationship.
It surprised you, just a little. You knew he hated showing emotions besides happiness and the occasional happiness, but never tears. He never cried solely in front of you, at least.
He felt weak, so… pathetic.
And on the other hand, you were there, trying to help him and coax some coherent words out of him, before finally giving up with a sigh
“Kats, if you don’t wanna talk, then we can save that for another time. I won’t push you any further if you’re getting uncomfortable.”
He’s never felt comfort like this. Not warmth, or such gentleness either. It’s so new to him, but in the best ways that he couldn’t describe.
What was this feeling? His heart was bittersweet now. His loathing towards Midoriya was worsening, but the sweetness in your voice was making it fade away slowly.
“I promise I’m fine,” he rasped out.
“Okay, Kats. As long as you’re alright,” you murmured, not really pushing him to speak unless he really wanted to.
He took a deep breath, not sure how to address the issue.
“Look, I don’t know what to feel when you’re talking to that damn Deku,” he stated plainly.
“You don’t know what to feel? What are you talking about?”
“I’m not stopping you from having friends, okay? I just don’t like how giggly and shit you were with him,” he huffed.
“Well… why not?”
“It just bugs me, that’s all. Just feel like I should be the reason you’re laughing. Not him.”
Oh. It finally clicked in your mind. He was jealous. You wanted to point it out, but it could sour his mood further, so you decided against it for the time being.
“Well, if that was the case, you could have just told me. I wouldn’t have a problem with that.”
You were too sweet, too understanding. It was hard for him to believe that he deserved it. That he deserved you.
“Really?”
“Yes, really, Kats. You don’t need to worry that I’ll be upset, okay?”
He nodded slowly, still not used to this amount of sincerity and care from someone.
He was never this soft, or vulnerable to anyone. You, however, were an exception. He wasn’t afraid to show it to you, and even though he wasn’t used to it, he sure as hell wasn’t complaining.
“Thanks…” a soft mumble of thanks left his lips, happy how this confrontation went.
@angelshimaa angst for you :)))
