Steve/Darren (the Darren Shan series) is totally Harry/Peter because it is all about how your life gets totally f**ked up when your best friend gets bitten by a spider.
Murata/Yuuri (Kyou Kara Maou!) is TOTALLY HARRY/PETER because it is about the way a geeky, nerdy, bespectacled best friend who gets beaten up by bullies all the time is actually SO SO SO MUCH MORE.
Oh, and the bitchslap that changed the world. Don't forget that one. :D
