Summary
Five years after Frisk freed the monsters, the multiverse began to collapse — merging every version of the Underground into one fragile, uneasy peace.
The Sanses and Papyruses of those worlds have learned to coexist. All except one.
The original Sans keeps his distance, isolated and withdrawn, haunted by something no one talks about — least of all his brother.
When Underfell Sans (“Red”) loses a drunken bet, he’s forced to ask the other Sans on a “date.” What starts as a joke turns into something much more complicated. The quiet, nervous skeleton he meets isn’t cruel or bitter — he’s broken, polite to a fault, terrified of making anyone angry.
Red can’t stop thinking about him. About what could make someone so kind so afraid. And about why Sans flinches every time his brother’s name comes up.
As Red digs deeper, the truth he uncovers will test every assumption he’s ever made about family, love, and the kind of monsters they’ve all become.
Themes: Trauma recovery, found family, abuse and healing, love as redemption, identity across multiverses, breaking cycles of violence.
