Lin An’an is forced to bind to a villain system and ends up transmigrating into a Western fantasy novel as the wicked stepsister, Hera. According to the plot, she is supposed to bully the kind “Cinderella,” Doria, but every act of “cruelty” secretly hides an attempt to protect her. Then, by accident, Doria’s tears trigger a system bug: whenever Hera comes into contact with Doria’s bodily fluids, she uncontrollably blurts out her true feelings.

Doria, who appears gentle and fragile, is actually possessive and obsessive. After discovering Hera’s secret, she deliberately uses tears, saliva, and more to force Hera into confessing. As the two become increasingly entangled in this push and pull between “villainess” and “yandere,” they also join forces with the original story’s “villain” to expose a royal conspiracy, break free from fate, and bring everyone to a happy ending.
