These are my FINAL sentiments here about this. I am not angry, I am not trying to be rude. If you honestly took the criticism as rude I've got no idea what to tell you other than I'm laughing so hard I may get a stomach ulcer.
Now you've got to believe me when I tell you this /IS/ plagiarism. As someone who writes college level essays and has to know plagiarism like the back of their right hand, I consider you take my word for it. Hell, look it up yourself if you feel the need. You don't have to steal the ENTIRE story for someone to find this, get pissed, show someone important, and get legal action taken against you because Stephanie Meyer or whatever her face is had a bad day and she felt like dropping the law hammer on a teenage girl that decided to use nearly her entire work for a fan fic.
And I honestly don't give a fuck who likes being called what to be honest.
This is NOT your own idea. The characters and a few of the circumstances are different (eg- main character is secretly English/British for whatever reason) but this is still plagiarism.
