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