You keep saying Harry would choose to stay with Tonks and that he wouldn't be forced to do it, but let's face it: he is being forced to do it, he is being forced to stay. You're making him stay, you're forcing him to go through all that. No one else.
Because it literally goes against everything that is in the character of Harry Potter to submit to anyone to such a degree as you intend to write.
Harry Potter, quite simply, doesn't take shit from people like that. You're writing an OC for all intents and purposes. Stop pretending this has anything to do with Harry Potter at all.
And yes, I will be here, in every chapter, reviewing and pointing out the flaws in the story. For as long as you keep writing horribly, I will be there to point it out.
