Hogwarts had been rebuilt and Headmistress McGonagall had accepted any 7th years from before the war to return if they wanted for their last year. Draco returned for reasons only known to him and his family, he was part Veela, and all this time he had known who his Mate was, but was selfish. He only wanted someone like him, but after the war He realized how awful it would be to have someone similar to him. As Half-Veela, his Veela senses were heightened emotions and feeling as if his heart could burst with joy whenever he saw her, but he had been able to control it and hide it until this year. Half Veela won't fully come into their 'inheritance' of being most like full Veela until their seventeenth year. It was his last year to get her to fall in love with him or he would die on his 18th birthday.
