Alpha Katsuki is mandated to go to an anger management course at the hospital and accidentally attends the anxiety disorder support group where he meets omega Izuku, and he is immediately enchanted by the adorable smaller man.

Katsuki gets to his group early every time.

He lingers in the hallway, hoping that he'll maybe just catch a glimpse of him. He's in awe.

There's just something so sweet and pure about the unsure man. At the same time, he's also mind-boggling.

Katsuki couldn't comprehend feeling unsure or worried.

At least until he met Izuku. He always knew exactly what he wanted to do and say and never regretted anything. But with Izuku... he felt nervous.

Every time they saw each other coming and going from their respective groups, the omega would give him that wobbly smile of his.

Katsuki would wave back, trying to smile but it always came out like a grimace. He felt embarrassed. What if Izuku thought Katsuki didn't like him? Or thought he was too rough?

The smaller man was so skittish all the time. And Katsuki was so big and quick to anger.

He didn't want Izuku to be scared of him, so he tried his best in his classes, learned a lot of skills to use to cool himself down.

Sometimes he'd bring little gifts for Izuku. A flower he found on his walk there, a candy bar he picked up at the store.

"Here," he'd grumble, cheeks pink and eyes averted in his embarrassment. "I don't need it, so..."

Izuku would always give him a blinding smile with that bubbly laugh of his. "Thanks, Kacchan."

However, Katsuki's class was ending soon. Only a week or two left.

He was worried, a foreign feeling. What if his class ended and he never saw Izuku again? Before he started, he would have been so eager for it to finally be over, for him to have completed the mandated class.

But now?

He wouldn't get to see that freckly face.

He had to do /something/. But he didn't know what. He never put effort into getting someone to notice or like him before. He didn't even know if the gifts were working.

He waited after his class finished for Izuku's to get out, kicking at invisible dirt on the tile floor.

A handkerchief clasped tightly in one hand.

Suddenly, the door to Izuku's group flew open, plenty of omegas and betas shuffling out, eager to get home. Izuku was one of them, but he slowed when he saw Katsuki.

"Kacchan!" he chirped, approaching the alpha.

"Hey... um," Katsuki muttered, taking a deep breath. "I.. wanted to give you this." He shoved the handkerchief at Izuku.

The omega tugged it from his grasp, a confused look on his face. The fabric was saturated in the oil from Katsuki's scent glands, aroma wafting off of it.

Izuku's eyes went half-lidded, but he struggled to maintain focus on the conversation. "Wha... what is this for?"

Katsuki glanced away, cheeks burning. "This is my last class, so.. I wanted you to have something so you wouldn't forget me."

"Oh, Kacchan," Izuku sighed.

"I haven't been able to forget you since we first met," the omega murmured, voice warbling with nerves. He sniffled. "This... um.. it smells really good."

Katsuki blushed. "I can always... make you more."

"May-maybe," Izuku stuttered, eyes watering with nerves.

"But maybe we could see each other... not at the hospital?"

The suggestion punched the wind right out of Katsuki, and he had to take a long moment to recover.

"Uh... yeah," he choked. "Yeah. Yes."

"Oh," Izuku gasped, relief on his face. "Thank goodness."

Katsuki could only stare.

"I, um," Izuku, "I've been practicing how to ask you to do something for weeks now.. They were helping me in group. But I was too scared until today."

Katsuki's chest felt /tight/. Izuku was looking at him with those wet green eyes.

Saying /he/ wanted to spend time with Katsuki.

"I've been practicing, too," Katsuki admitted quietly, averting his gaze.

A quiet moment passed.

"Can we," Katsuki began tentatively, "go to the cafe and... talk?"

Izuku grinned, a blinding smile that flipped Katsuki's stomach.

"I'd like that a lot, Kacchan," Izuku replied, a questioning gaze on his face. "Can I... hold your hand?"

Katsuki flushed cherry red, looking anywhere but at Izuku. Still, he blindly extended his hand, feeling as Izuku's fingers clasped just his long pointer finger. Fuck. Cute.

"Thank you," Izuku murmured, tugging gently on the finger to encourage Katsuki to follow along.

The two walked side by side down the hallway all the way to the exit. Katsuki ignored the stares of his former classmates, all the while Izuku blushed, smiled, and waved.

His group members were so happy for him, smiling at him as he passed in the hallway.

They made their way to the cafe across the street, both blushing and unable to hide the small smiles bubbling onto their faces. They were too happy.

And even if Katsuki got mad that the line was too long or angry that they messed up Izuku's coffee, he remembered the feel of that tiny hand clasping his finger and felt a wave of calm pass over him.

Izuku let Katsuki scent him for real before they left.

Leaning down to rub their necks together was positively euphoric. He'd never felt something so good in his life, and judging by Izuku's shivers and tiny whimpers, it seemed like the omega felt just about the same.

Katsuki said goodbye to Izuku after walking him back home.

He felt warm, clutching and staring at his phone.

He had Izuku's number. And he would see him again. And again. And again.

How could he be angry when he remembered that?
