Summary
After a string of after-party scandals lands him in rehab, top model Katsuki Bakugo is sent straight from recovery to a working ranch in the middle of nowhere. Ranch life is all early mornings, callused hands, and work that doesn’t stop just because you’re tired, and it demands a patience Katsuki has never learned. He’s expected to earn his place fast
Eijiro Kirishima, the ranch foreman, doesn’t have time for distractions with winter closing in and a crew already stretched thin. The new arrival reads as trouble: loud, green, and out of place. Miscommunications linger, tempers flare, and neither of them is in a position to want more, yet the quiet, unspoken pull between them grows anyway. Out on the range, where trust is built slowly and nothing comes easy, they learn that some bonds take time, grit, and a willingness to stay.
Or: KiriBaku goes a little Brokeback Mountain with a Hallmark cliche.

Where The Water Lets You Leave by DemonicDomain

Summary
He spent six years in captivity, experiencing the horrors of humankind.
Katsuki just wanted to go north to find his family again, to let them know he's still alive. Kirishima finds him and promises to get him there after the winter thaws. That's it.
It was supposed to be temporary. But somewhere along the way, the water changes. A place where mers are safe. Where younglings are raised in the open. Where humans don't hunt. A place where no one is kept unless they choose to stay.
Katsuki doesn't trust it, doesn't trust the humans. He definitely doesn't trust the way his body reacts: to the water, to the others...to Kirishima. Because if it is just instinct, he can leave.
Right?

Summary
When Bakugou Katsuki's life goals come to a screeching halt, he does the only thing he can think of--disappears. After all, who would come after the anti-social asshole?
Kirishima Eijirou, that's who.
Refusing to accept that his best friend has just abandoned him, he goes looking for him. But the Bakugou Katsuki he finds isn't the same one he knows. Pregnant, alone, and suffering, there's no question that Eijirou is going to step in and take care of him. As his best friend, of course. That would be the manly thing to do. And if he gets to prove what an excellent alpha he is in the process, well. That's just a bonus.
But when the truth of Katsuki's pregnancy comes to light, it will not only put their newfound happiness at risk but shake up the entire hero world.

Summary
“Then shall we make a bet Kacchan?”
“A bet?” the blonde raised a fine eyebrow.
“If I do make it. If I become a hero, then you will become mine.”
---
In a land where it was impossible for omegas to become knights and heroes, Katsuki could only watch as Deku left to try and become what Katsuki could only dream of. He would take great joy though in seeing the idiot return to admit his inevitable failure. Katsuki was very much looking forward to winning their bet.What Katsuki didn’t know though was that when Deku would finally return, Katsuki would no longer be there. He’d be a captive, being taken to a frozen hellscape by a redheaded savage.

Summary
"You're a mermaid."
The raucous laughter at the counter died instantly as the stranger froze mid-motion, his mug remaining hovering an inch above the wood while the entire room seemed to lose its collective breath.
Two massive vivid crimson eyes, reflective like polished gemstones, turned to fix Katsuki with an intensity that should have been terrifying, but the silence lasted for only a moment before the creature's lips split into a wide grin that revealed rows of sharp, triangular teeth.
"And you're a pretty human."
— or the one where katsuki moves to a remote fishing village to research mermaid folklore for his book, only to realize the stories are real when eijirou becomes the first mermaid he ever meets.
