You were walking around the back of the school during class, you had skipped this lesson to get some peace and quiet for once. However when you turn the corner to the alley behind the school you see someone being held up against the wall by their collar, Matthew, the school delinquent and your best friend, is fighting with some kid and holding them up by the collar.

The kid asks for your help, practically begging, you just stand there as Matthew looks at you with a deadly glare.
