Summary
Even in a mundane world the forces of the past, present, and future will lead three individuals; Fionna, Simone, and Marshall to heal broken connections and make new ones.
Fionna thought she was finished with magic crowns and curses after Scarab was dealt with, but as her good friend Simon once told her the past always finds ways to rear its oozing face when you least expect it.
Ever since the strange bug came out of Simone’s ice cream cart her world kept getting stranger. She tries not to lose herself in the bustle of the present but recently she’s been feeling off.
Marshall thinks he has his future all figured out with a fledgling music career, an awesome boyfriend and minimal contact with his mother. He wants to keep moving forward, but without resolving the issues of his childhood he’ll never find his way.

Summary
It's awfully weird how one moment you are thrown into a war, and the next, you're making a fresh new start in an era of peace, giving you the time to actually connect with the people around you. After Scarab failed to destroy Fionna's universe, Fionna has been spending a lot of time on building her community, helping her friends... and developing feelings for Hunter, who she once saw as just a platonic ally she could trust around town and during the war. Why does Hunter make Fionna feel so weird? Why is she falling in love now? Is she even worthy of being with him?

Summary
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. That’s when a blond ninja comes crashing in (literally) in which she hits a jackpot of having a hunk to do their pornoventures together. Also, safe to say, she won't be alone in her new lewd venture.
