Chapter Text
Katsuki watched.
That's all he really could do without looking like a total dick, and he was actively trying not to be. He owed Izuku that much. They'd come a long way, and he'd realized a lot about himself.
The first, most important thing: Katsuki always seemed to be too late.
By the time he had realized exactly what Izuku meant to him, he'd surrounded himself with friends who deserved him.
And he'd gotten himself a girlfriend—someone who deserved his time and attention.
The girl, a second-year from the General Studies, had insisted that they call her Sachi-chan. Katsuki called her Frilly Fuck. Izuku had spent an ungodly amount of time explaining that nicknames were a sign of respect. "Otherwise he'd call you an extra," he chuckled.
She'd smiled good-naturedly. "I figured," she'd replied. "I mean, why else would he call his best friend Shitty Hair? He even calls you Deku, and you're not useless at all!" She pressed a kiss to his cheek, and Katsuki averted his eyes.
She was wearing fucking bows in her hair.
She looked picture perfect tucked into Izuku's side and Katsuki hated it.
And it wasn't just because he was being petty. At least, he hoped it wasn't. There was something about the way she smiled when Katsuki was near. He didn't know why but it didn't feel right.
It had been four months since Izuku had introduced them, and that nickname had been coined. Katsuki had been playing nice. Well, as nice as he was physically capable. "The fuck, nerd? You said you were gonna meet me twenty minutes ago," he snapped.
Sachi smiled sheepishly.
"Sorry, Katsuki," she said. He grimaced. She'd insisted on using his name, and he actively hated the way it sounded coming from her. "I might have distracted him."
She interlaced her fingers with Izuku's, and his eyes were drawn to the movement against his will.
"Well fuckin' stop it."
"No, it's definitely my fault," Izuku sighed. "I thought I'd set my alarm. Sorry, Kacchan," he apologized, sincere and earnest in a way that made Katsuki feel like he'd kicked a woodland creature.
"Don't fuckin' apologize, just don't do it again," he snapped.
Sachi's sweet smile tightened. "Oh, come on. He works so hard. Give him a break, it's not like he ditched you completely."
No, just partially. He bit that one back. "He slips in training now, next thing you know he'll slip in the field. Then you won't even have a boyfriend."
"Kacchan!" he whined. "I'm not that bad, I wasn't gonna skip!"
"Mhm. Sure. Now let's fuckin' go, dork," he said, turning to go.
Izuku made to follow him but Sachi caught his hand. "Aren't you forgetting something?" she asked.
He smiled and pecked her on the cheek.
Katsuki's gut churned as he waited by the door. "They're cute," someone sighed beside him. He nearly jumped out of his skin.
"The fuck, Cheeks?" he snapped. "Don't fuckin' do that!"
"Don't you think though?" Ochako asked. "She's super sweet. They're really good together."
He glanced back at them, holding back a wince as he tucked a hair behind her ear. "She's fine. But she's a fuckin' distraction, too."
"Hey, we're heroes," she protested. "Gotta take the good stuff when it shows up, or else we'd just be miserable all the time."
A part of him wished he counted as 'good stuff' but he knew better. He was endured, not enjoyed.
He watched them as she kept him there a little longer, then longer again—pulling him back down to kiss his cheeks, then his nose, then his chin, then his lips. He hadn't seen Izuku smile like that in so long.
"Deku!" he snapped a moment later, finally losing his patience when she wove her arms around his neck to lock him in place. "I get that you wanna suck face with the Frilly Fuck but we only have the field until five!"
"Wah! Sorry!" he yelped, unwinding himself from Sachi.
"I'll come over when you're done?" she said, asking it like it was a question when they all knew it was a fact.
"Yeah! I'll even cook," he grinned.
Katsuki sighed, and Ochako giggled. "Yeah," he quietly agreed, catching her attention. "They're good together."
Izuku caught up a second later. "Ochako!"
"Hey!"
"Enough fucking socializing, Deku, we're late!"
"Someone's grumpy," Ochako grumbled. "Better get going, or else he'll blow something up. Probably you."
"Fuck you!"
"Hey, Sachi! Wanna come hang out while you wait?" Ochako asked, already brushing Katsuki off. "We're gonna study English by watching American reality TV," she giggled.
Katsuki's mood soured even further. She was infiltrating his life. But that was the thing—she seemed nice enough. He didn't get why it bothered him so much.
Well, that wasn't totally true. It was probably that everyone around him seemed to like her better. That would grate on anyone, right?
"You coming, Kacchan?" Izuku asked.
"You're the one who was late, nerd!"
