Fic idea where Jaskier is a fae who keeps breaking into Kaer Morhen despite everyone's best efforts.
He doesn't want to hurt any of them (obviously), he just thinks the Witchers are cool and wants to shower them with affection. So he breaks in every winter and brings them food and helps fix up the keep and makes sure they're okay and sings them songs.
The Witchers are understandably very upset and freaked out by this random fae breaking into their home every winter. They spend so long trying to ward the keep against him, they try chasing Jaskier away, there are multiple attempts on his life. Jaskier just laughs and boops them on the nose before fluttering away. They end up reluctantly accepting him like one of those wild foxes trying to domesticate themselves.
Jaskier then starts kidnapping leading other Witchers to Kaer Morhen and the keep eventually fills up with very confused, very grumpy Witchers and a very satisfied fae who's happy with his collection.
