High School AU based on this Tumblr post Sam and Dean are forced to go to high school while John is hunting, Dean notices a shy boy called Castiel. They start dating, but Dean breaks his heart. Years later they meet again. Multi-chapter with a happy ending. (Will be sad sometimes!)

Cas and Dean met one night, strangers in a bar, and one thing led to another. But by the next morning Cas had gone. This is the story of them reconnecting, despite initial misunderstandings, and Dean's persuasion that Cas take a chance on him. Destiel Human AU. Extended to include Gabriel/OC relationship development in later chapters.

[AU Fic] Castiel and Jimmy travel back to their hometown of Lawrence to celebrate their older brother Gabriel getting hitched. Of course, staying with the Winchesters means staying with Dean, Cas' high school boyfriend whom he did not exactly part on good terms with, which leads to angst, awkwardness, and a possible opportunity to fix two broken hearts, all in twenty five days.

Destiel AU. Mechanic!Dean bombed a proposal. Business!Cas is on the mend after a break-up with his boyfriend. How do two such different men meet and fall in love? And can it last when Cas's world starts to implode? Features nosy brothers, plotting friends, great music, corporate espionage, and Kitten!Lucifer. Humor/Romance/Drama! *Adding four new end-extras 31OCT15*

With a heavenly fall comes a bundled miracle. After seeing a winged man leave an infant in the backseat of their car, the Winchesters take Castiel into their family. Unbeknownst to them, Castiel included, he's an angel and his people's last hope. Destiny calls on him in the throes of high school drama and puberty, he isn't ready. OC Jet Please review!

Haunted by a dark past, Castiel's life hardly improves when he gets to high school and becomes the target of the school's most popular jock, Dean Winchester. Dean's fascination with Castiel is mistaken for something twisted, and just too late does Dean realize his intentions towards Castiel to be of love and not hate. (Warnings: Bully!Dean, noncon/rape, socially anxious!Cas)

Castiel Novak meets Dean Winchester in high school but they never really talk and when they do everything changes and they don't see each other until three years later and Castiel tries his best not to get sucked into himself and run away. And of course not to get sucked into the green eyes that haunts him. Writer!Cas and chef!Dean and kind of High school/CollegeAU

Dean fell in love with Castiel when he was fourteen years old and he had no idea how to handle that. Thankfully, with the help of his family and friends, he learns how to deal. Dean/Aaron Bass John/Mary mentioned Castiel/Meg and Castiel/Balthazar eventual Destiel (High school AU where everyone is human and everyone lives)

Castiel is a boy trying to make it on his own, a boy no different from the rest. Except, of course, for the pair of ocean blue wings he's hiding underneath baggy T-shirts and sweaters. He's antisocial and prefers to stick to himself. That is, until a boy named Dean Winchester starts turning everything upside-down. Destiel, high school AU.

Their families have forced Dean Winchester and Castiel Novak into dark places to survive. Will their friendship help them deal with their desperation? [Destiel.] [Samifer.] [High School AU.] [Slash.]

Destiel, w/ a side of unrequited Sam/Cas. Dean is in his final year of high school and Sam is starting his first. Things are meant to take the easy route but the arrival of the Novak family will end up making their town famous.
