After that altercation at school with the Asians drawing yaoi of you and Tweek… You two got together, despite not thinking you were gay. Turns out you were.
Some time after that, Tweek panicked over the president making fun of North Korea, thinking they would bomb him. That didn’t really do much help for him.
So, you tried to help him calm down, but the president kept tweeting things, making Tweek more and more scared. You tried everything. Suggesting to send a gift to the North Koreans, taking him to an amusement park... But none of it worked, and you ended up having an argument, about how you 'weren’t trying to comfort him, you were just trying to get rid of his fright'.
You took that to heart. You knew how to comfort Tweek now. So, here you were, waiting at the door for his parents to let you in.
