As Proud As Love (слэш)

Some idiot invented a potion after the war that gives whoever consumes it the characteristics of a Veela—and people keep taking it to find their mates or impress their lovers. A shame that the transformed people are violent and leak allure until they find their true mates. Harry Potter, immune to the Veela allure because of his unrequited love for his ex-girlfriend, provides guardianship for transformed Veela against other people and their own impulses until they can find their mates. Guarding Lucius Malfoy should have just been another such duty. But Malfoy is taking an unusually long time to find his mate.
