Harry Potter Fanfiction: The Old Days

Someone transmigrated in the most cliched way imaginable. Someone thought she was a special case in this cliched setting. She never expected to be brought back down to earth so quickly... As it turns out, this is an HP world that's been conquered countless times. All right. You don't read fanfiction for nothing. After fighting the boss a thousand times, you can't just fail to clear the level. There's a tank (Ron), DPS (Harry), and support (Hermione). The monster-hunting squad is on the move. And as for someone... she just tags along to soak up the experience. Huh? Why isn't the ending what we were promised? Apparently, this is a slash fic. I'm a canon fan, so there'll be no pure-blood aristocracy or platinum-haired legends... And no saving the professor or drugging Uncle Snakeface... The male lead is Harry (a rare pairing. The author absolutely refuses to admit she decided to write this because there were so few fics for this ship). I'll try not to make anyone OOC... I'll try... Ahem, a serious warning: Slytherin fans, professor fans, and Voldemort fans, run for your lives...
