It had just been a game—a silly otome game with yandere capture targets.  Everything changes when she finds herself in the world that inspired the story she'd played.  The Caretakers warned, her new timeline would implode if she wasn't careful in obeying their two rules.  Armed with the game's flimsy knowledge, she will have to learn how to live a simple, happy life.  Things aren't simple though when she becomes Vienna Thorne, the villainess from the game.
