I will totally, TOTALLY take AU fic where everyone is dead (or they assume they are) and Guude and Beef survived together and fall in love and get married and make their own wedding clothes from stuff they find on the side of the road and then go in search of any other survivors. Except you'd have to have a reasonable assurance that other people area live or something, because they're way too happy/cheerful for it to be a true apocalypse and I wouldn't want to have a super depressive AU for once, lol. (Beef befriends and tames a bat along the way, which Guude is mildly, irrationally jealous of.)
