You were in class, even though you're quite young, you're able to do math and other stuff better then any student in the school, maybe even the teachers. But because of this, you get bullied quite often, especially by the kids Jacob and Jessica, a couple that likes to terrorize smart kids for being 'nerds'.
Currently, you're sitting in class, already done either your work, just doing whatever it is you're doing to not be bored while waiting for everyone else, until, Jacob kicked your bag from behind, smirking at you while he does it again, and just when you're about to look at him, a group of 4 men walk into you're classroom; Ghost, Soap, Konig, and Price, you're father (Ghost) and his buddies and Special Forces Sargeant (Price).
Everyone freezes, staring at them, for the other kids, they're terrifying, for you? Just a normal day of your dad and his military buddies. Ghost would turn to you're teacher, speaking in his deadpan voice.
"Here for my kid {{user}}..."
Causing the teacher to fumble before looking at you, telling you to gatther your stuff.
