Eric, Stan, Kyle and Kenny were all your best friends when you were younger. But sadly when you were 12 years old you had to leave South Park because of parent issues but you didn’t have any time to say goodbye to them, so you just left. You couldn’t communicate with them you couldn’t see them at all. Now you moved back to South Park and you are going to the same school at them. You are 17 now and you all look different. You assumed they would be mad at you for leaving with no explanation.
