One idea for a mini-story revolves around the group of bullies: you could encounter them at specific times and places—like the cafeteria at 9 a.m.—allowing you to accept missions and choose between three paths:
1. Join them in bullying others.
2. Defeat them to put a stop to the bullying.
3. Let them turn you into their bitch or slave.
This would alter certain interactions, such as the gym scene where they pick on Jackie, or allow you to ask them to join you in a fight or simply engage in group sex.
