AU meme → Dean/Castiel as university professors who embark on an inter-department romance
Dean Winchester lived a pretty simple life. He read novels, graded papers, and went to his brother’s for dinner on Sundays. He liked it that way. His routine was good, it was safe, and he’d never really entertained that something might be missing—that is, until Castiel Milton came long. Cas was not the strangest history professor Dean had ever met, but he certainly was the most fascinating. He was eccentric and intense, and four types of handsome, and somehow Dean brought about a smile in him. It was only a matter of time then, really, before they became the talk of the school.
