When the Underground goes dusty and silent, Sans decides not to follow the plot for once, and something from another dimension starts peeking through them like a window… Imp has to decide if leaving the house was really worth all the trouble of taking on two world’s worth of problems.
(Jevil-centric OCs, Undertale/Deltarune crossover fic, slowburn romance with lots of tragic yearning, set in the Genocide Route and Weird Route respectively. Themes exploring some game theories and disability in context of one’s environment. Trigger warnings for ableism, blood, and gratuitous murder.)
