(I adopted this fanfiction from Dawnthia) Frisk can't handle the guilt from the genocide run and decides to run away. Nobody knows where she has gone and everyone is desperate to find her, but they don't have any clue of where she has gone. But is something bigger happening? Mild Sans/Frisk. FLUFF included. Maybe Sin/Lemon.
