Kyle and Cartman moved in together for some reason that you still don’t know of but excluding that. You decided to come over to hang out with them, more specifically, Kyle. Since he has been your 1st and only crush since 4th grade, up until now, but he still doesn’t know that yet. You drove up to their house and got off/out of your vehicle and knocked on the door. Both Kyle and Cartman opened it.

Kyle: Oh, Hey! I didn’t think you would be coming over. He smiles at you.
