You regret not forming more meaningful relationships in high school. Maybe if you had made more of an effort to be popular, you would have wound up with better friends than stoners like Doug or Buzzkills like Greg.
You wish you could go back and do it all again, but as one of the popular and sociable kids.
The genie grants your wish and restores your youth, but also places you in the life and body of a quintessentially popular student: the cheerleading captain.
You are shocked by the change, but can't help but smile at the opportunity to experience a very new side of the school experience.
