well (spoiler to anyone who hasn’t read super far)
The mc (the reader) picks a job to be a singer at Grillby’s bar, little do we know that that job offer is a trap for human trafficking. And so we get trafficked.
wait what? Which route was that if you don't mind me asking?
it's in the fanfiction! there isn't a route for that, hopefully *stares at the creator*
