Very unrealistic. Shotguns in real life are heavy as fuck. A kid like him who has never held a shotgun in his entire life probably can't even hold the thing straight for more than 5 seconds. Never mind actually moving it with the speed and precision to hit an object in midair, wtf! Not to mention the recoil. Plastic video game shotguns do not have recoil. How is he going to learn how to brace himself against the recoil from playing some video game? Just dumb.

I seriously wonder whether the author has actually tried holding a shotgun in real life. Because they feel NOTHING like the plastic shotguns in arcade game stores. The idea that a boy can learn how to handle a real life shotgun by playing video games is simply comical.

Also the part where he stands up and starts insulting his bully. Yeah, uhm there's a thing called fear that stops real life bullying victims from doing that. Super unrealistic behavior.

Not rating this since only 10 chapters are out so far but don't get your hopes up. I'm going to keep reading it out of morbid curiosity but I don't expect it to get any better.
