"Izuku!" {Izuku/male!classmate one-shots}

Kirishima/Izuku

"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.
