When Gamzee takes it up a notch in his attempts to court Dave into being his kismesis, Dave decides he can't just ignore it any more. Cue lengthy Karkat Vantas rants and awkward teenage boy fumblings. Slightly aged up AU where everyone is one big, dysfunctional family on the meteor while they wait out their three years.

“Bro?” you ask, reaching up to rap on his forehead with your knuckles. Somehow your hand just tangles itself all up in his fine-ass hair and you sort of yank and turn and then two of you are kissing. It’s sloppy and hot and awkward, the angle all wrong and neither one of you used to each other at all, but when he gets your lip between his dull choppers and bites until you’ll bruise it’s just about motherfucking perfect.

Dave doesn't always understand the nature of troll romance, but most of the time he doesn't need to.
