I really like this :3 the title got my attention straight away and I think for your first fan fiction, you're writing it better than some people who only write fan fiction. I like the development of the characters and it's great you've managed to do it so well after only three chapters, y'know?
I think your writing style and grammar are pretty much perfect too. I really love how you've described Gerard the most though because the detail you've put in about his depression and drug problem is really deep and intriguing.
Overall, this is awesome, you are awesome and I can't wait for more ^.^
