You were ready to drop by the time you got back to the dorms, you’d been working overtime with Fatgum, Kiri, and Momo. They were just as exhausted as the three of you made your way back. When y'all split, you and Momo went to change and check on your mates while Kiri went to grab a snack. Imagine your surprise when you arrived at your room to find it desolate, Katsuki’s nest empty and the room cold. You shrugged it off, he’d been acting weird the last few days, you hadn’t had the chance to check in with him until tonight. He was probably just in the common room with Denki and Mina or something, so you just showered and got changed, then went to look for your mate.

You checked Denki’s room first, but that only contained the wrong blonde, and shinso was over so you moved on as quickly as you could, following Katsuki’s scent to the common room and freezing when you got to the door. There was your mate, cuddled up to Kiri, who’s terrified eyes darted up to meet yours. Your stomach dropped when you saw Katsuki rub his cheek over Kiri’s scent gland. Okay, so it was like that, huh? If Katsuki wanted to be with Kirisofucking badly, who were you to stop him? So you didn’t say anything, pushing down that hurt feeling, holding your breath and making a point to ignore Katsuki as you walked through to the kitchen, scent taking on a sour scent you couldn’t do anything to stop.

Of course you ignored Katsuki on the way back, too, not even glancing in his direction as you stormed back to the rooms, going past your room and knocking on Deku’s door. It swung open a few moments later, Deku’s shocked face peering up at you, Shoto behind him sitting on the bed.

“Katsuki is being a dickhead, is it okay if I stay with you guys for a bit? I brought gifts.” The last part was emphasised by you producing a blunt, and Deku was quick to nod and let you in, closing the door behind you.

“So, what’d he do this time?” Shoto opened the window, making room for you to sit with them on the bed, Deku grabbing the ashtray for you.

“He was just all over Kiri, so I figured if he wants to hang with Kiri so bad I’d let him, and come hang with you guys!”

“Hanging with Denki wouldn’t make him mad enough so you came to Deku and me?” You almost missed Shoto’s smirk, and you couldn’t help but grin.

“Aww, you know me so well!”

Okay, that hadn’t happened the way he’d planned it, Katsuki thought you’d say something, maybe pull him off and back to your room, not completely ignore him. It wasn’t his fault you hadn’t been giving him enough attention, what else was he meant to do other than make you jealous?

“Hey Bakubro, don’t uh, blow my head off or anything, but Y/n is hanging out with Midoriya and Todoroki….” Denki’s words had Katsuki jumping up from where he’d been next to Kiri, looking like he’d been slapped across the face as he bolted out of the common room. Why the fuck were you with Deku? That wasn’t safe- that shithead fucking omega and his fuckstick alpha would steal you away the first chance they got if he didn’t save you! Of all the people, why the fuck did you have to go to him?

The three of you were watching a movie, with you squished in between them, which you couldn’t help but think was kinda odd. The two of them were dating, you had no idea why they’d want you in the middle, but maybe they were just trying to stop you feeling left out? Then Deku rested his head on your shoulder and you froze, heart skipping a beat when the omega rubbed his cheek over your scent gland- What was he doing-? Shoto was right there and- since when had his hand been on your thigh?

“Um- guys- what’s uh- what’s-“

“Youwanted to make Kacchan jealous, didn’t you Y/n? I’m just helping!” Deku pulled away so he could look at you, feigned innocence the only thing you could see in his eyes, he knew you weren’t the smartest, and he’d treat you so much better than Kacchan if you just let him-

He went back to covering himself in your scent, Shoto’s thumb rubbing circles on the exposed skin of your thigh-

Then the door was thrown open, a growl cutting through the haze of the room, and you were being yanked out of the room and thrown over Katsuki’s shoulder before you could process what was happening.

He was too angry to speak, slamming the door to your dorm, locking it to make sure there were no unwanted visitors, and then he was pulling your clothes off, ignoring the way you tried to kick him off.

“Katsuki- what the fuck-“

“You fucking reek, Y/n!” He finally snarled, and you shut up, letting your omega strip you down to your underwear, quickly pulling on the hoodie he threw at you. Fuck, he was pissed- honestly you were glad he’d come in, you weren’t sure what would’ve happened if he hadn’t- you were still pretty high, if you were being honest.

“What the fuck were you thinking?” Katsuki sat down next to you, anger still coming off of him in waves as he brought his wrist to your neck, rubbing his scent gland so aggressively over yours, you couldn’t help but flinch.

“Uh- I was um-“ It was hard to think, you were already exhausted from work, and so much had happened since then- “You were just uh…. On Kiri so I thought I’d… uh…. Go hang out with them… since you were busy…” You trailed off, you could barely talk, let alone think of lying to him. Katsuki had to bite back a snarl, you were so fucking dumb, just his big dumb alpha, huh?

“You fucking idiot, I was trying to get your attention, I’ve barely fucking seen you all week, you haven’t fucking scented me in days- but if you’d rather hang out with Deku-“

Oh, well, that made sense, you didn’t waste any time pulling him into your lap, rubbing your cheek over his scent gland and peppering kisses over his neck, you could feel the anger melting off him.

“Shoulda just said so, you don’t need to pull that shit with me Katsuki, you know I don’t pick up on stuff like that.” You leaned back against the wall when you were satisfied, resting your mate’s head on your chest and letting your fingers play with his hair. He didn’t respond, just grumbled as he pulled the bedcovers over you, but his scent was back to the warm caramel you were used to, and it wasn’t long before the two of you were dozing off.
