Summary
After the war they spent two years repairing and rebuilding their relationship. They'd lived together for a few months now, and had fallen into each other's habits and routines easily. He'd learned to let Kacchan cool off when any playful anger went too far. And Katsuki had learned to soften his jabs and support the crybaby hero he lived with. He confidently busts down the door of Izuku's room and drags him out to the couch to watch a movie until the nerd either talks or cries all the worries out of his head.
But Katsuki never lets support be reciprocated in that way. He may yell, he may complain, Izuku will still let him spar out his frustration, but when it comes to comfort or vulnerability... Well it's never been Kacchan's strong suit. Izuku still tries to find ways under that armor.

Summary
Katsuki stares at the wall in front of him. A vein pops on his forehead.
So, everyone thinks Katsuki can’t handle an alpha long-term, huh?
That’s what this is. They think he’s not good enough for an alpha. Just because he’s a beta.
Well, fuck all of them.
Or; beta Katsuki’s downward spiral (and then comeback) while dating the very irritating, pathetic, and annoyingly loving alpha, Izuku.

Summary
And don’t even get him started on Izuku.
Because if there’s one alpha on this planet who seems hellbent on dragging Katsuki into the pheromonal fuckfest he wants nothing to do with, it’s that curly-haired, over-eager, green tea-scented menace.
Or; Katsuki is a beta just trying to live his life in a world full of alphas and omegas. One alpha makes that hard. (And even harder when a mission's safe house happens).

Summary
When Katsuki released his wrist, Izuku slowly withdrew his touch but couldn’t look away from the green handprint now circling the other alpha’s throat. It was an unmistakable mark of claiming. Blood roared in his ears.
Mine, his thoughts snarled, violent, insistent. At his back, he could hear his ram stomping his hooves and tossing his head in a show of dominance. Similarly, Katsuki’s wolf had gone still, and he stood tall, tail rigid, teeth bared, and eyes glowing.
Despite accepting Izuku’s mark on his skin, despite welcoming it on the most vulnerable part of his body, Katsuki was still an alpha staring down another alpha. For the first time, though, the thought didn’t worry Izuku. Instead, it exhilarated him.
