Fionna was down on her luck when she quit her job, remembering there is another way to get work. She feels uncomfortable with the idea since she wants a boyfriend to make it with.

Summary
Simon is such a fatherly figure to Finn as he grows up, kind, caring, and always there when he needs a shoulder to cry on or a question answered.
It's easy to see why the Hero thinks of him as a parental figure. But you shouldn't be thinking about your parental figure's naked body splayed out beneath you and them calling you a good boy though, right ???(( Finn has some mommy and daddy issues. ))

Simon has been alone for so long. And he had thought he would always be the last of kind, doomed to the empty existence.

Someone with cat ears and a tail, and Simon hoped not to ruin his first interaction with his kind for... maybe a hundred years. But damn, did his body have the worst timing...
