Cocktail bartender Lin Yan transmigrates by accident and inherits a dilapidated tavern in a fairy-tale world. It is home not only to fairy-tale characters with regrets, but also to a mysterious door leading to fairy tales across countless worlds.
Though she cannot use magic, she has a one-of-a-kind gift: using the sincere tears of a beauty and the relieved sighs of a beast as ingredients, she brews magical drinks infused with emotion.
And so, the strangest tavern in history, Between the Stardust, opens its doors. It serves drinks that can heal the heart, and is dedicated to rewriting the fates of fairy-tale supporting characters and helping them overcome their regrets.
When Cinderella becomes a pastry chef, Little Red Riding Hood takes a job as a security guard, and Snow White just wants to read in peace, Lin Yan discovers that her tavern also maintains the balance of the entire fairy-tale world.
