The Reborn Side Character Transmigrates into a Book: When in Rome

[Second chance at life + transmigrate into a book + slow burn + sweet romance] Su Qianwan, the young lady of the Loyal and Brave Marquis's household, went to war clad in armor and drenched in blood to help her husband, the Second Prince, seize the throne. She was left covered in scars and disfigured. But on the very day the Second Prince ascended the throne, he accused the Su family of treason and ordered nine generations of them put to death. As she lay dying, she drank poisoned wine, and her soul fell into the Heavenly Dao's realm. There, she discovered that her world was actually the novel The Undefeated Huangfu Aotian Conquers the Realm and Becomes Emperor, and that she was merely a supporting character. The Heavenly Dao granted her a sliver of hope, allowing her to be reborn in another world and fight to become its protagonist. She was reborn as Chi Xiaoxiao, the real daughter and supporting character in the modern novel The Fake Heiress Rises from Sweet to Black and Becomes the Female Lead. Sharing one body with its original soul, she had assumed that the soul inhabiting it was dead. But it turned out the soul was still alive, and had even set a trap. Using the bond between soul and body as a medium, it forced Chi Wanwan (Su Qianwan) into the female lead's role, stealing her protagonist's aura and reducing her to an ordinary person. The original soul would take her place instead... She started dating someone who seemed to have a split personality. He described himself as: cuddly or wolfish, cool or sweet. She thought of herself as: a girl with several boyfriends ૮ ºﻌºა
