Alright, this is a fairly decent story, but I noticed a few small issues on this. The action moves a bit too fast, and you could benefit from taking a read over or beta reader. But oterwise, I like the idea behind this, and the general feel of it. Would like to point out however if he shot people in school he probably would've been unable to make it back home. And is the Andy we're talking about here Andy Biersack (Six)?
