After Transmigrating as the Villainess, I Became the Heroine's Mouthpiece

After Transmigrating as the Villainess, I Became the Heroine's Mouthpiece Plot:

A modern office worker Su Xiao stayed up late to finish a tragic romance novel, only to transmigrate into the book as the villainous supporting female with a tragic ending. She just wanted to cling to the heroine and survive quietly, but unexpectedly unlocked the ability to read the heroine's inner thoughts. She accurately voices the unspoken sarcasm and sharp retorts from the heroine's mind, slapping the scumbag ex-husband and scheming rivals in the face. She not only shakes off the original death flag, but also accidentally forms a wonderful bond with the abstinent male lead. However, she gradually realizes that her actions have quietly rewritten the original plot of the novel.
