Whenever a character, usually a man, lies about who they are or uses a false personality to meet or woo their love interest, it is Love Under False Pretences. Usually the lie will be revealed and often the love interest will eventually forgive the character who lied to them and take them back. This happens a lot in Rom-Coms like Wedding Crashers, There's Something About Mary, Hitch, Coming To America, The Ugly Truth, Just Go With It and She's The Man. Compare Loves My Alter Ego, which doesn't necessarily happen under malicious pretenses, and usually is to protect the person. Also compare Playing Cyrano.
