Wildfire Lily

Leora, a broke fast-food worker, dies in an accident and wakes up inside a novel as the wicked stepsister. The system gives her a mission: push her sweet stepsister Maren's corruption meter to 100% and she will get a hundred million dollars and a ticket home. To get back, Leora torments Maren in public while secretly protecting her. What she never expects is that the innocent-looking Maren is a full-blown yandere who has hacked the system and heard every one of Leora's true thoughts. Faced with such fierce, deep devotion, Leora gives up going home and chooses to stay for love.
