[Underswap Papyrus x reader]You have a secret. You are the last of your kind, shapeshifter / Human hybrid. The very culmination of your being constantly pleads for you to be honest about who you are, but your kinds law prevents you from doing so. Will you be honest and open about your powers with your new friends, or will you continue to lie and hide in the dark? (Yes the title is a pun, if you aren't aware bonafide means honest/ trustworthy, yes the title contradicts itself it's supposed to show the struggle between logic and emotion.)…
