Every time Frisk dies, a little yellow flower grows on their body. This dimension stars the Underfells, and Frisk. Eventually Frisk has so many flowers that she goes blind, and relies on the kindness of others, mainly UF Sans and UF Flowey. This is a UF Sans x Frisk story, because I LOVE that ship.
*Seeing that there's a lot of Undertale AU one shots and lemons in the discover fills you with DETERMINATION. Warning: 18+ I can't stop you from reading though so be responsible if you'll proceed lolMature
