Summary
Katsuki had never not gotten what he deserved. Growing up he was the best, and so he was constantly told he was. It was just what he deserved, a truth of his life. He was powerful, had a powerful and heroic quirk, and was going to be the number one hero, and everyone told him. Even Deku.
He got the best grades, had the best looks, and had deserved the best because of that. Deku may have been quirkless, but that was just so Katsuki had the best person to protect. The weakest of them all was right next to him for a reason! Deku was useless, was nothing without Katsuki by his side to keep him safe, he just had to realize that.
-
When the Bakusquad discovers their explosive friend's real motivation behind wanting to become the number one hero- to win the heart of a boy- they decide to stop at nothing to get them together. Until they see how he treats him that is.

Summary
Awareness was inching through his body in fits and starts as his brain tries to catch up with each new sensation. His head is so heavy still so he lets it fall back onto the helpful man’s shoulder, nose tickling his neck. He smelled nice, campfire smoke and summer nights that made him want to snuggle deeper into that scent. Izuku tries to shuffle around but he can’t find his arms, resulting in him nuzzling into the stranger’s neck.
“You’re being so good little hero, I think that means you deserve a treat,” the rough hand on his chest groped at a pec, squishing the muscle in his hand, “do you want a treat, omega?”

The League of Villains has a plan involving a certain omega on how to bring about the downfall of hero society, they just have to pup him first.

Summary
He shouted out something like “OI. DEKU. BEER PONG. NOW.” and it worked like it always had. Green hair and eyes came into view and all that mattered was getting the freckles that came with under him. In scoring. In rank. In something. He gestured to the table with an explosion.
In beer pong, it seemed to be.
It would be enough. This had to be enough. Just one more challenge.

Katsuki has apologized, he and Deku have even been rebuilding their friendship. So why isn't it enough? -

Summary
After leaving teaching behind for a less than dramatic return to heroics, Izuku is assigned perpetual nightshifts to ease the transition. Initially, he finds the dark hours peaceful, but when his coworker goes on sick leave and he has to patrol solo, he’s concerned about the creeping loneliness.
All of that changes when a crow appears, stalking him, stealing his coffee flavoured snacks and in shocking twist, helping him arrest attackers and chase thieves! Izuku wonders: Could it be the guiding crow god, Yatagarasu?!
Shouta meanwhile, is in a concealed state of misery. His co-worker and secret “unrequited” love has quit his job. Initially he thinks it's a good thing. He can finally lock away this pointless affection and focus on teaching… until a rare opportunity presents itself. A way that he can be close to his treasure without making a mistake and ruining their strictly professional relationship. With this, he can bask in all that beautiful warmth and enjoy those sweet, intelligent mumbles.
Maybe being the victim of a quirk attack is an opportunity, not an affliction…
