Now that Hermione Granger and Ron Weasley have been dubbed the highest grossing on-screen couple, it makes sense to turn to Hogwarts for dating advice. The magically gifted ladies are happy to oblige, with one girl from each house giving her advice on approaching that cute girl in your potions class and the hazards of kissing with braces.

The moral of this story? Don't date a guy who is friends with a Slytherin girl. And watch your braces around Ravenclaw.
