Steven Rogers is a sixth year student at Hogwarts School of Witchcraft and Wizardry when he happens upon a Slytherin student named James Barnes or, as he prefers, "Bucky". To the discomfort of their fellow house members, the two grow closer as Steve attempts to help Bucky with his spells. Bucky soon learns the reason behind Steve's passion for defence against the dark arts and is there to help him move on from his past. [A Steve Rogers x Bucky Barnes Hogwarts AU]
