[Harry Potter] The Battle History of an Anti-Sue

Hey, Merlin, aren't you being a little petty? Just because I cursed you before going to sleep, you dragged me into an HP world full of Mary Sues! You say it's to bring balance to that world, but I don't feel even a hint of a protagonist's aura around me! How am I supposed to compete with those dazzling Mary Sues? This is a cheerful, snarky story with no romance at all, just the tale of a Chinese otaku whose not-so-peaceful daily life gets a little magical. I'm terrible at writing blurbs, so go easy on me =w=
