I don't know if they have a tumblr or anything, but I finally caught wind of the vintage UT Asgore-centric fic "Day to Day" by CourierNew, and aside from a couple dated things HOLY SHIT ITS SO GOOD??? Impeccable Asgore characterization, and holy shit Perserverance's chapter in particular hit SO hard like wow its nearly everything I could want out of a previous human/Asgore encounter
So I drew a little slice from that chapter that really did it for me
