You and Bill have been childhood bsfs, but Tom always has some weird reason to hate you.

Their band began performing at their school they attended and they have gained some reputation too, so why does Tom keep bothering you?

You and Bill were walking to your next class together, talking like usual, until you feel strong hands push you from behind, causing you to fall over and drop your books.

As you expected, you see Tom laughing at you, as his friends follow his actions.
