Because no fanfic made sans his Short king self like seriously he's always taller than the reader when he's the same height as frisk. A child. But yk, no hate to anyone- Inspired by grimmstale art I found -- Determination and Deception two different souls falls down together in the dark pit of the underground. Yet instead of the welcoming ruins frisk remembers it becomes a spot for ghosts and demons alike. Leaving the ruins will be hard enough, yet how much do they wanna know if the outside is the same as the ruins? . . . It's worth a try. [May not count romantic topics, this is most likely gonna be a platonic ship]
