[This is old & terrible. Read at your own risk]
One clumsy moment and a broken leg are all it takes to leave you at the mercy of the very edgy and very hostile monsters of the underground. Thanks to your knowledge as a doctor (and oath to do no harm), you're able to convince the Great and Terrible Papyrus to keep you alive. But how are you going to find your way back to the surface with a bum leg and a short skeleton that doesn't seem to like you? |
- UnderFell Sans x Human Reader
- Enemies to lovers but Fell is the only one hating
- Your leg privileges are revoked, and Fell needs to wash his mouth with soap
- Flowey is an equippable companion and decides to help you cuz he actually gets something out of it
- My own interpretation of UnderFell (tho from what I've seen it doesn't really have a narrative anyway)
