Lin Anan was forced to bind to a villain system, reincarnating as Hera, the malicious stepsister in a Western fantasy novel. According to the plot, she must torment the kind-hearted “Cinderella” Duoliya, but each act of “bullying” secretly hides her protection of her. One day, an accident occurs: Duoliya’s tears trigger a system glitch—whenever Hela comes into contact with Duoliya’s bodily fluids, she loses control and speaks her true feelings. Though Duoliya appears fragile, she is actually a yandere. After discovering Hela’s secret, she deliberately uses her tears and saliva to force Hela to confess her true feelings. As the two become increasingly entangled in the tug-of-war between “villain” and “yandere,” they join forces with the original “antagonist” to expose a royal conspiracy, break free from the shackles of fate, and secure a happy ending for everyone.
