AU: Aziraphale and Crowley graduated from high school, after school Crowley goes to university in some big city, Aziraphale stays in their hometown. They are school friends (they have not yet realized that their feelings go beyond friendly ones). For a whole year they stay in touch: text each other, call each other, read the same books and go to the same movies, so that later they can discuss what they read or saw. During the year they become closer than just friends. At the end of school year, Crowley realizes that he no longer wants to be so far away from Aziraphale, and he is transferring to the university in his hometown to be with Aziraphale. The end ❤️
