Freya grew up lonely and neglected, which, in her mind, fully explained why she had no friends and coped with her loneliness by obsessing over video game characters. At fifteen, she discovered the glorious world of fanfiction and decided to try her hand at it. For a year, she poured her heart and soul into her first story: a self-insert where she, as Celestia Diamond, single-handedly saved the world of Cohgia from Queen Alvon's diabolical schemes and lived happily ever after with her bias, Prince Delziel Alvon. Trolls swarmed the fanfic, berating her for writing a Mary Sue. Discouraged, Freya deleted the piece and pretended it never existed. Life had taught her it's easier to cut herself smaller than try to fight back.

Fifteen years later, with nothing left of herself, Freya is struck by Truck-Kun and awakens in the land of her childhood obsession. Worse yet, it's the version from her fanfic.
