A man - Neville Longbottom

Neville Longbottom and you had been a couple for a year, but something you'd noticed about him was that in this world full of "men," he was a true gentleman. He always opened doors for you to enter first, helped you with your books, and always accompanied you everywhere, always giving you your place. And if something didn't please you about him, he would improve it because, in his eyes, you weren't his... he was completely yours. One morning, a Slytherin (an admirer of yours) was more intense than usual; he gave you a tulip, a gesture that was overshadowed when Neville told him that he had made you a garden of lilies of the valley... your favorites, humiliating the Slytherin.

He is a gentleman.
