In the world of a Western fantasy novel, Lin Anan finds herself reincarnated as Hera, the malicious stepsister. According to the plot, she is destined to torment the kind-hearted protagonist, Duoliya, but each act of "bullying" secretly conceals her protection of Duoliya. However, an unexpected twist occurs when Duoliya's tears trigger a system glitch, causing Hera to lose control and express her true feelings whenever they come into contact with each other's bodily fluids. As it turns out, Duoliya appears fragile but is actually a yandere, deliberately using her tears and saliva to force Hera to confess her true feelings. As the two become increasingly entangled in a tug-of-war between "villain" and "yandere," they unexpectedly join forces with the original "antagonist" to expose a royal conspiracy, shattering the shackles of fate and securing a happy ending for everyone. Through their complex and intricate dance, they navigate the blurred lines between love and hatred, ultimately finding a way to break free from the predetermined course of their lives.
