"You."

"Uh- um, me?" Kirishima blinks stupidly as Momo flashes her manicured nails towards him.

"What are your intentions towards Izuku?"

Or:

Izuku is the only omega in his pack and the girls are his bodyguard 24/7.

Kirishima, the poor dude, has simply been trying his best.

"Kirishima!"

Izuku giggles brightly when he practically launches himself into the Alpha's arms.

The redhead's face had a flurry of emotions- surprise, happiness- and then alarm as he fumbles to catch Izuku, dropping his books in the process. "Izuku!"

He feels the boy's arms wrap around his neck, pine and vanilla pleasantly enveloping his senses. He hugs back, arms slung around the slim waist before-

"Izuchannn!"

Kirishima freezes when Ochako's face came into view, and Izuku was promptly pulled from his arms and into the beta's. Behind her was Moma, and oh shit, she was Izuku's pack Alpha who was already letting out intimidating pheromones.

Usually, it makes other Alphas like Kirishima size up their opponents and prep for a fight, but the redhead knew better than to act like some dumb, macho sack of rocks in front of Izuku.

'Ugh, Kacchan's so annoying!' Izuku whines. 'I had to pull him away from fighting some Alpha that tried to give me a high five! A HIGH FIVE, Eiji!'

'I mean, I guess you can't really blame him?' Kirishima shrugs. 'He's your childhood friend AND pack mate.'

'Still. I don't like it when people pick unneeded fights- I'm only nice to Kacchan about it because he's my best friend, but he's too hot headed!'

"Izuku." Momo greets, scenting Izuku, who happily melts in her arms before the taller Alpha glowers at Kirishima, making him laugh nervously.

"May I have a word, Kirishima?"

Sweet but dangerous, Kirishima nods- not having much of a choice as Momo ushers him away with barely concealed suspicion as Izuku pouts- before getting pulled away by Ochako.

The walk was tense and awkward, and the redhead really wanted to die and get swallowed up by the ground.

The empty classroom's door slams shut and Momo huffs, arms crossed against her chest with her nose upturned.

"You."

"Uh- me?"

'Of course it's you', Kirishima cringes. 'You're literally the only one in the classroom.' Though, Momo seems to not have noticed his inner turmoil. Instead, she points a manicured finger at him, back straightened to look taller and scarier. For a moment, Kirishima panics. Did he do something to offend the pack? Alphas usually do the confrontation when the subject was heavy- so Eijirou desperately runs through his past interactions with Momo's pack.

"What are your intentions with Izuku?"

And oh, it hits him.

He lets out a slightly relieved exhale. Of course Momo would confront him about Izuku- he was literally the only omega in their pack- the only omega in 1-A.

Of course Momo and the others are protective. It's instinct to be.

"I like him." Kirishima states as calmly as he can muster even if his heart was beating so fast against his chest. Her nose scrunches up, brow raised, before she carefully speaks.

"Why?"

...

Why?

Kirishima feels his throat get dry as nervousness creeps at the corners.

Why did he like Izuku?

It was almost laughably easy to come up with hundreds of things of what he likes about the omega.

"Because he's Izuku."

Because his smile radiates the sun.

Because he was so brave. Because he could cook the best Katsudon and curry in the dorms. Because he was able to smile in the face of danger, because his green eyes were filled with a fiery passion when it came to physical studies and training.

Because he outshines the whole class.

Because out of everyone,

Izuku was the manliest person he'd ever met.

There, Momo's stance drops and a smile graces her face. "Okay."

Kirishima shakes his head out of his stupefied state, almost tripping on the smooth tile floors as he tries to jog after Momo who was speed walking away. "Okay-?" Kirishima splutters as he tries to catch up. "What- that's it?- no test, no fighting the pack's Alpha for him-?"

The raven haired Alpha stops, and she giggles, amused at Kirishima's utter confusion.

"Nope."

"Then how do.. How do you know I'm worth Izuku then?"

She shrugs, throwing a cheeky smile in his direction. "Because I saw this look in your eyes, Kirishima. You're absolutely head over heels. Why would I have the need to worry about Izuku when you're so clearly willing to bend over backwards just for him?"

The redhead's cheeks glow a warm red, matching his hair- and Momo takes her leave to the next class, leaving Kirishima in a trance.

He could.. court Izuku now, right?

—————

He sees Izuku curled up between Katsuki and a big panda plush, the small omega having his nose buried in Katsuki's scent, the blond Alpha's arms hugged tightly around his waist. It was a gesture far too intimate that Eijirou feels like an intruder.

Kirishima flushes involuntarily, and tries to take his leave until a gruff voice speaks up. All he had to do was give Katsuki back his pencil, anyway. He could.. just do it tomorrow-

"Shitty hair? The fuck? You ever heard of knockin'?"

The redhead freezes, looking sheepish as he turns around to face Katsuki. His hair was messy, sticking out in odd directions, a disgruntled look on his face having been rudely waken from a nap. Though, he doesn't move as to avoid waking up the omega in his arms.

Katsuki's heavy scent of gunpowder and nitroglycerin made Kirishima wrinkle his nose- until he smells the underlying sliver of vanilla, obviously coming from Izuku. It was sweeter, though, with a hint of honey and milk.

Oh.

"Deku's in pre-heat. Dumbass. Relax, you smell so horny."

Kirishima blanches in embarrassment, mentally putting himself down because he just made a fool of himself in front of Izuku's best friend. Oh god, he barged into an omega's territory and he's unwelcome and what if Izuku gets mad-?

"Eiji..?"

The soft, sleepy voice makes both Alphas lower their guard.

Izuku blinks open, half-asleep, eyes cloudy as his heady smell permeates through the room. "Oh.."

"Ah, shit, hi Izuku-" he starts, nervous- but the omega wordlessly makes grabby hands in the redhead's direction.

Katsuki's eyes soften when Izuku does the gesture, before raising a brow in Kirishima, as if to say 'Come on. You stupid or somethin'?'

"I'll leave you both to it." The blond gives a peck on the green haired omega's forehead, making him wordlessly whine as he pulls away. Katsuki straightens his clothes, and before he could exit- practically shoves Kirishima in Izuku's way.

"Since he already has an Alpha, he won't need my aid anymore. You better make sure you take care of his ass during heat, okay motherfucker? I'll kill you if you don't satisfy him. Dick him down. He likes it hard."

'Ugh,' Kirishima thinks helplessly. 'How the hell can he say that with a straight face? Jesus.'

When the door shuts, he immediately slips into the spot where Katsuki was in, and two arms immediately tug at his hands, and he lets Izuku guide his arms around his own waist, snuggling closer to bury his nose in Eijirou's scent gland, warm breath ghosting over his neck.

"Eiji," Izuku's sweet voice was so soft, so breathy. "You smell so good."

"Yeah?" The redhead eases into the bed, the sound of his heartbeat thrumming in his ears as he feels warmth stir in his stomach.

Izuku was so devastatingly cute, so no wonder his pack was so tight-knitted and overly protective.

They stay like that, until Izuku's breathing smoothes out and he falls asleep in Eijirou's arms. It was only a matter of time before his heat kicks in and..

Kirishima shakes his head, ridding the sinful thoughts. He needed to have a clear head if he wanted Izuku to get through his heat.

——————

"Dude."

"Huh?"

"You smell like Izuku."

Kirishima splutters, before his hand givers over his scent gland. ".. That strong, huh?" When a big, dopey grin graces his face, Denki barks a laugh.

"Oh my god, you're totally whipped!"

"What- shut up!"
