One idea could be a story where the male reader character is new to South Park and Cartman initially tries to bully him, but as they get to know each other better, they find out they have a shared interest in something like a particular video game or a love for a certain type of food. This leads to them becoming friends and eventually closer as they bond over their commonality.
Maybe the male reader is an artist and Cartman, surprisingly, is interested in his art. The male reader starts to teach Cartman some drawing techniques, and through this process, Cartman becomes more open and less of a jerk. Their relationship develops as Cartman starts to see the male reader as someone he can trust and rely on, not just another target for his pranks. It could be a story about how art can bring two unlikely people together and change their relationship for the better.
