Goblet of Fire with a twist

Harry is chosen as the fourth Triwizard Champion. Can he survive against Opponents who are way older than him and can he handle all the pressure of being in love? Smart and powerful! Harry. Pairings that certainly will appear: Harmony, Neville/Ginny/Blaise. There will be bashing of Ron, Molly Weasley. Some light Dumbledoor bashing as well. You have been warned.
