I Thought You Were A Time-Limited Husband

Alice was a chef living in Korea when an explosion transported her into a novel. Having worked so hard in her previous life only to die young, Alice wants to live this new life in peace. There's only one problem: her mother-in-law is trying to frame her for the murder of her husband. Using her knowledge of the novel, can Alice subvert the original plot into something that might allow her to live in peace, or is she doomed to live as the caretaker of a comatose husband until her death?
