Good boy, Badass boy

Domenico Pietro de Cerintti, in the eyes of everyone was the good boy, the sacrificial lamb, the one who attended all the classes and obeyed all the rules, the one who would not let a puppy get run over by a car, the one who didn't have a girl in his bed every Friday night, the one who didn't smirk, the one who girls liked but never wanted, the one who girls used and dumped, the one who wasn't badass. He lived with that image, was content with it even with the bullying until a certain day when they crossed the line, the one line they were never to cross. He disappeared. And appeared months later, in college; the college that had a good percent of his highschool student in attendance; changed, for the worse. Rosetta D'armani, one of his mates in highschool and now his mate in college, who never bullied him but who also never saved him from the bullies. She was, as defined by the male folk, hot, sexy, drool worthy. She saw him on his first day back and lusted after him. She followed him, sought after him, chased after him with every breath in her. He made her lick his heels. After all he was badass now. He smirked now, he had girls in his bed not only every Friday night but every night, the girls wanted him, he used and dumped them now, he was badass. But oh...those bullies didn't know his definition of badass. Badass for him meant revenge. He would revenge on each one of them including his beloved girlfriend. He'd show them just how hot badass burned. One mysterious girl, one desperate girl, one perfect girl and one revengeful boy. ???
