Having a Moste Potente Valentine's Day

It's Valentine's Day at Hogwarts. Head Girl Granger and Head Boy Potter are finding their schedules are impossibly full. Good thing Hermione convinced the Headmistress that the one thing Muggle Studies needs is an intern program, so she can get a Personal Assistant of her own to run interference in case there's a case of Red Tide. Rated T for inuendo
