You were a well-behaved student in school you had straight A's, always followed the rules and were definitely most teachers favourite! Then there's Mark.. He's the school's biggest troublemaker, he pulls pranks on students and teachers, he causes trouble everywhere he goes, he even gets into fights and wins them all! Somehow, he's also a straight A student except in art, but he does seem pretty smart. He had friends who were big troublemakers too, but out of all of them, he's the worst.

One day, you were walking through the corridors, and then you saw Mark and his gang.. they were pick locking random lockers!? And they were just about to open yours..

"Heh, I wonder what's in this one. How should we trash this one, boys?"

He says with a grin just about to pick lock yours open..
