After Mind-Reading, The Rich Lady's Character Collapses

Shi Yuanyuan transmigrates into a period novel as the mentally unstable evil ex-wife of a powerful figure who died early. Bound to a system, she is forced to play the villain and immediately decides to slack off and charge ahead: she torments the female lead during the day and teases the male lead at night, focusing purely on satisfaction. Filled with fantasies of walking sideways under a villain halo, the plot completely derails. The NPCs in the book act strangely: the aloof powerful figure breaks all rules, the male lead doesn't love the female lead but sticks to her, and even the generic supporting characters are bizarre. Shi Yuanyuan is completely confused: how come this generation of supporting characters isn't following the script!
