'Til When Will We Part? (Reaper!Sans X Geno!Sans)
17 parts Complete A crack opens in a breaking universe and Death peeks through to the other side. It seems like this "code" thing hasn't been doing it's job, and there's someone who's long in need of reaping. Death tries to relieve Geno of his suffering though, well, himself, but when that fails, there's no choice but to relieve his suffering some other way, right? Perhaps they could help each other.
