PROMISE. // Bakudeku

So Fucking Strong.

IZUKU SPENT THE rest of the day staring off into space. He was now seated in the common area of the dorms, holding a cup of tea in his scarred hands. Iida and Ochako were sitting on either side of him on the couch, explaining their tardiness to class this morning.

"Anyhow Midoriya," Iida stressed, "it's with my deepest regrets that I ended up late on my first day. It's disgraceful. I intend on apologizing to all of my fellow classmates. Excluding you, Uraraka."

Ochako gasped humorously. "I know I made you late, but what would you do if a child asked you for directions to his school? I had to listen to the poor kid's terrible description of his elementary school and it took forever to find."

Midoriya was barely listening, but he managed to keep the impression that he was listening going. "So what's a kid doing without his parents, though? On the street like that. Some people shouldn't have kids." He mumbled the last bit under his breath.

Iida firmly agreed with the first half of the statement, before ranting on about the hypocrisy of some adults– all while karate chopping the air with a single hand.

Izuku felt as if the world became fuzzy. His skin began to feel warm, and his leg muscles seemed to go slack while tightening at the same time. His eyes widened slightly, frown deepening in thought.

The greenette, as a side effect of having dysfunctional scent glands, had an irregular heat cycle. This burden has caused him a few embarrassing moments growing up- it seemed as though his heat insisted on starting at the most inappropriate and random times.

It was a good thing he caught on to it quickly.

He strained to not release any pheromones (although what he released was many times weaker and virtually unnoticeable to betas- which his friends were), and mumbled an excuse about being tired before racing to his room.

Midoriya never told anyone his second gender. He wanted to be treated equally to the betas and alphas that made up 95% of U.A.'s population. Only a select few teachers, including All Might of course, was aware.

It helped that Izuku was a scientific rarity. His pheromones were virtually next to nothing, so even if he went into heat, he wouldn't disrupt the class with a strong omegan scent. The irregularity countered that, though.

To keep his heat under control, Izuku had to regularly take heat medications. In short, he's never had a heat on campus before due to his constant dosage.

He'd somehow forgotten to take his medication over the break, though.

Izuku whimpered. Drool slipped past his lips, and slick dripped down his legs, soiling his pajama pants in the process. He clung to the railing of the stairs.

He panted. I want-

"Midoriya?" Izuku's head snapped to the direction of the call.

It was Todoroki.

Izuku felt his insides turn, and he desperately tried to control his breathing. His friend was an alpha, and a very sensible one at that. He would catch on if Izuku wasn't careful.

Shoto stepped closer. Izuku could've sworn he saw the grey-blue eyes of his friend gloss over with curiosity and lust. Maybe it was the lighting.

"Are you okay?" Todoroki asked calmly, eyeing him closely.

The boy was certainly attractive, Izuku always knew that. In fact, he'd always had a small crush on his friend– nothing compared to his longing for Katsuki though.

"Y-yes," Izuku managed, almost cringing at the weak, whiny tone of his voice.

Shoto sniffed, pupils dilating instantly. The faintest hint of a scent invaded his nostrils. It smelled so environmental and non intruding that he almost missed it.

Jasmine....and is that mint?

The staircase smelled like a garden.

Izuku stepped further away from the ice user, grabbing his room door handle.

"I'm fine, really. I just...I've been using scented shampoo. I'll be going now."

He shut the door behind him, immediately opening his windows to let some fresh air in.

Todoroki was a special case. He only smelled him because of his extremely close proximity, and his high end instincts. He had his DNA to thank for that.

Izuku slipped his clothes off, staggering over to his bed. In his hazy state, he couldn't manage to give a fuck about finding his medication.

He helplessly squirmed against the sheets.

There was nothing to worry about. It didn't matter if Izuku opened the windows; no one would smell anything.

Or so he thought.

What's that fucking smell? Katsuki froze.

Kirishima was laying down beside him on the bed. "What's wrong? Why am I smelling you, you horn dog?" He laughed.

They were currently in Bakugou's room, playing video games.

Katsuki scowled. "I'm not horny, don't be gross. I just- I fuckin' smell something."

Kirishima leaned back with a frown, trying his hardest to pick up a scent. Nothing.

"That reminds me." Ejirou hesitated. "I don't like the thought of you going into rut over some omega or beta's scent. We should-"

"I don't want to be marked." Katsuki knew exactly where his boyfriend was heading.

"I respect that but why-"

"Because." Bakugou gritted his teeth, feeling his senses go haywire. Was the scent getting stronger?

"Because I'm not...ready for that." The blonde almost rolled his eyes. The truth was, he wasn't attracted to his beta partner in that way. That'd be the green haired nerd instead.

Katsuki would rather die by hot oil than admit that, though.

Kirishima chuckled half heartedly. He felt like there was no convincing him. "I'll uh, be going. I'm sleepy."

"Fine," Katsuki muttered, observing him.

After his boyfriend left, the blonde poked his head through the door, trying to find the source of the smell.

Most people were asleep. Hell, he'd be too if the smell of a garden didn't almost cause him to go into a rut.

Next to his room was Ejirou's on the right, and Izuku's on the left. He certainly knew that Ejirou smelled like nutmeg and spice.

He exited his room, leaning his ear onto Izuku's door.

Whimpering?

His eyes widened.

Katsuki opened the door slowly, not thinking as he entered Izuku's room.

The scent of Jasmine, along with traces of other plants like mint and roses, hit him instantly.

As his fiancee, he knew of the greenette's secondary gender, but he'd never smelled his scent before, thanks to Izuku's constant supression and Bakugou's refusal to be near him.

On the bed, Izuku was sprawled out. He then curled into himself, shaking and panting in his sleep.

Katsuki was dumbfounded, but he slapped his palm over his nose. This was really, really bad. He had to leave before he lost his senses and felt things he didn't want to feel.

He left, making sure to close the door behind him.

As he struggled to forget the image of Izuku's naked body twisted between the bed sheets, a barrage of questions flew into his head.

Didn't this dumbass have a gland problem? Why is his scent so fucking strong?
