i never came up with an actual name for this one, but i love it to bits either way.

a handplates au where gaster chooses mercy at some point after putting the plates on. sans is distrusting, but papyrus is forgiving, so he naturally grows closer to the latter... perhaps closer than he intended.

as gaster tries to bury these unwelcome feelings for papyrus underneath his fatherly ones, sans’s intuition is telling him that something is very, very wrong.
