Lisa is a card-carrying, book-loving Gryffindor. Solid. And that's why everyone knows she's awesome. Well, except for her crush, Matt. He only ever sees her as a friend. Plus, he's got his eye on another girl. Oh well, plenty of fish and all that. Good thing Lisa just read a book on the "wedding ring phenomenon"-you get more attention when you're already taken. What if Lisa pretends to be Matt's plus one? Maybe it'll help Matt get his girl...
