Fair maden (Stan Marsh x reader) (based on the black Friday episodes)

Y/n is Cartman's cousin who recently moved in with Cartman, of course, Cartman wants you to join in. You're the one person he slightly tolerates and he wants you to be on his side through everything, knowing that you're very strong.
The timeline is a bit screwy but it's basically a self-insert (for you) into the episodes in season 17, the three about black Friday. However, all characters are 16.

P.s: I haven't seen Game of thrones, so it's solely based of those episodes in south park.
