So. Here's the dealio. We all live in a city by the name of Perry. Everyone lives in harmony. Wanna know why? Because we're invincible. But there's a catch. Every persons age 18-22 gets a letter in the mail, saying who they're to marry. Of course, you can still have a boyfriend or a girlfriend, have sex, be bi or gay or lesbian or whatever floats your boat. But once you get that letter, you find out just how invincible you really are.
