Xiao Yanfei, after transmigrating into a book, believed that her identity was not simple, as evidenced by the following: 1. She was a concubine’s daughter in the Marquis’s household, but her appearance was unparalleled. 2. Her legitimate sister was the female lead, currently engaged to the Crown Prince. 3. She maintained a good friendship with the Second Prince, a villain character with an abundance of buffs. According to the laws of transmigration, she was undoubtedly an extremely important… villainous character. And she would sacrifice her intelligence, dignity, and even her life for the breathtaking love of the male and female leads in critical moments. At first, Xiao Yanfei just wanted to keep a low profile, avoiding “sacrificing” her life and achieving the worst possible ending. Later, she discovered that the original host had been switched at birth with the female lead, and she had even considered the villain as her birth mother. Under the “earnest guidance” of her stepmother, she willingly endured any hardship for the sake of the female lead. Meanwhile, the reborn female lead took over the original host’s identity, trampling on her tragic past and enacting a “breathtaking love” with the Crown Prince! Xiao Yanfei: …Tired. She rolled up her sleeves, sharpened her blade, and was determined to tear apart this melodramatic plot and set things right! The Second Prince, with a stack of villainous buffs: Do you need help?

With half of his face concealed by a mask and a scarlet robe billowing, he extended his hand to her amid thousands of troops and horses: “From now on…” “Those who follow you will prosper, those who oppose you will perish!”
