The female protagonist and the supporting actress were reborn and transmigrated to ancient novels respectively. The female protagonist's surname was Su, and the supporting actress's surname was Liu. The female protagonist was a talented woman but lost to the supporting actress, which eventually led to her death. Have you recommended any similar books?

I recommend the novel "The Female Cross-Ender" to you. The protagonist of this novel, Su Qingyao, also transmigrated into a novel and became a female supporting character. She and the female protagonist are enemies. However, Su Qingyao was not suppressed by the female protagonist. She actively resisted the oppression of the female protagonist and successfully turned herself into a happy female protagonist through her own intelligence and courage. The plot of the book was straightforward, the main character was domineering, and the female supporting characters were not all bad. The relationships between the characters were very complicated, and it was very interesting. I hope you like my recommendation. Muah ~
