Shortly after his 21st birthday, he meets a mysterious dark haired stranger, they become best friends, go on wild adventures together, and travel the world. Until inevitably, the best friend meets with a tragic fate, and Dean lives out his life alone and forgotten.
It has been 7 generations since the last Dean walked the Earth. And this Dean just turned 21. It's fine, really. This Dean has no intention of playing along. -

After losing his father and closing the family garage, he’s been drifting, half-living in a run-down house, working odd jobs, occasionally fixing old cars for the neighbours, mostly keeping to himself.

They meet at the starting point of a weeks-long walking route, part of a small group tour. Both signed up to get away from their lives, but neither expected to find each other.

Summary
In a world where borrowers are real, so are soulmates, and only one of them is commonly known about (hint: it’s not the the tiny people living in the walls).

Summary
After getting his wisdom teeth removed, Charlie, Adam, Cass, and Sam visit. Due to the anesthesia, Dean is completely out of it and is mostly a rambling mess.

Summary
When Dean Winchester meets the enigmatic and grounded Castiel, he isn’t searching for change—just a little something to call his own. But what begins as a quiet friendship gradually deepens into something more, as Castiel gently introduces him to a world where surrender is not weakness, but a quiet kind of strength. Through trust, vulnerability, and the slow unraveling of long-held fears, Dean begins to discover a sense of safety, acceptance, and love he never believed he deserved.

Summary
Dean's never seen himself as a particularly optimistic person.
But even if he had. He thinks he'd have had trouble feeling overly positive about his new owner. A thirty-year old weirdo, some lonely alpha shut inside a malfunctioning lighthouse like it's his own personal fortress. Plus, the kindhearted captain, reluctant to bring him up. The people in town, who don't see much of him.
Dean, about to be thrown to the wolves.

Summary
Castiel had bought the stamps with good intentions. He’d thought they might be a gentle counterbalance to the occasional academic brutality of his feedback. A harmless gesture. Encouragement. Positive reinforcement.
Apparently, they’re multipurpose.
Castiel smiles, teeth catching behind his lips. “You’ll get another stamp if you ask nicely.”
Dean exhales, eyes fluttering shut. “Fuck.”

Marriage and all the other mistakes we’ve made. by Meluene

Summary
Divorce - who doesn’t dread one? Unfortunately, it sometimes happens, leaving ex-partners to deal with the bitter aftermath.
Luckily for them, Dean and Castiel - very much divorced and quite happy with their now separate lives - left it all behind a few years ago. Everything would be great if they could just continue ignoring each other instead of dealing with a quite substantial inheritance that everyone seemed to be interested in. Well, everyone except for Cas and Dean, who would rather be sent to outer space than spend another five minutes in the same room.
Lost in the world of awkward discussions, a great deal of tension and many misunderstandings, they both just want to survive until the end of this situation.
Little do they know, fate has a completely different idea for both of them!

Summary
When Dean falls off a ladder trying to put up some Christmas lights, he finally gets to meet the next-door neighbor he'd been avoiding. Turns out Pastor Novak isn't a pastor anymore and is struggling to sort his life out just as much as Dean is. Neither of them is very good at accepting help, but they manage to get past each other's defenses and quickly become close. They decide to have a friendly competition to see who can have a better upcoming year. May the best man win.
---------------------------
There was a knock on the front door. Dean groaned, but went to answer it.
Castiel stood on his porch, holding out a store-bought pie. “I don’t cook.”
“Okay?”
“Everybody coordinated to bring you something, since we weren’t sure if you were going to be able to feed yourself when you got home. I don’t know if you saw that there were a few dishes in your fridge.”
“Everybody?”
“Well, everybody except me because I don’t cook.”

Summary
Omega slavery may be outlawed, but that doesn't mean the trade has stopped. FBI Agent Dean Winchester knows that all too well — which is why he's going undercover as a newly purchased Omega to get close to one of the most powerful families still trafficking illegally. His new owner? Castiel Novak.
Castiel isn’t what Dean expects. Quiet, sharp-eyed, and surprisingly kind, Castiel treats Dean less like property and more like a person — which would be a lot easier to ignore if Dean didn’t suspect there was more going on beneath the surface.
As Dean plays the part of a broken Omega and Castiel walks the razor's edge of betrayal, their shared mission draws them closer. Lines blur. Loyalties shift. And the deeper they go, the more dangerous the game becomes.
Because falling for the mark was never part of the plan.

Summary
Dean Winchester didn’t join the force to mediate furniture-based crises, but here he is, ankle-deep in particleboard, trying not to laugh while a stranger named Castiel loses a fight with IKEA.

Summary
Castiel’s a literature professor. Dean’s a mechanic with a ’67 Impala and a crooked smile. They don’t belong in each other’s worlds, but that’s never stopped them before. When Dean shows up at the university in the middle of Castiel’s lecture, everything from Emerson to office gossip gets a little more personal.
A quiet slice-of-life romance about love, self-reliance, and showing up, even when no one expects you to.

Summary
Castiel liked his coffee hot, but what he enjoyed even more was managing to get to his classes on time. Naturally the infuriating new barista from the coffee shop just outside the university he worked at didn’t seem to understand either concept.
Or, the one where Dean is a barista, and Castiel a university teacher. They can't stand each other.

Summary
“So where are we going?”
Dean’s heart nearly stops as he slams Baby’s brakes, grateful there's no one else behind them on the road.
He whips around in his seat, only to come face-to-face with a kid who is decidedly not Sammy. His messy blonde hair is cut above his ears (something he can only dream of Sam doing)and he’s quite a few years younger than Dean's brother, feet dangling off the edge of the seat and not really touching the floor.
“You’re not Sammy…” He tries to not break into hysterics. Sammy doesn't have a black backpack decorated with little embroidered honeybees, he doesn't wear Velcro shoes, and he certainly doesn't squint his wide blue eyes and cock his head to the side when confused.
“No,” The little boy answers carefully, “I’m Jack.”

Summary
Cas, quiet until now, shoots Dean a look that clearly says ‘be nice to your brother’. He’s glad Sam and Cas get along and everything, but they team up against him alarmingly often. Throw Charlie into the mix, and Dean is likely to never win another argument for the rest of his life...
Or like, whatever. He and Cas have only been dating for a few weeks. They’ll see where it goes. Dean isn’t totally ass over teakettle for the guy, or anything.
He likes him a normal amount.
***
It’s the Fourth of July. There’s a beach. There’s fireworks. Dean wears cutoffs. What more is there to say, really?
