A post‑Pacifist slow‑burn Sans/Reader romance about healing, magic, prejudice and found family.
You work in a bookstore. He’s a skeleton with a soft heart, dangerous magic and a talent for making you laugh, even when the world feels heavy. Papyrus adopts you immediately (and with great enthusiasm).
As monsters struggle to integrate on the surface, you’re pulled into Snowdin’s orbit: political tension, magical injuries, protective brothers, ensemble chaos and a relationship that grows from banter and awkward sweetness into real vulnerability… and eventually, shameless smut.
