Reborn as Cannon Fodder, I Outlive the Hero and Heroine

Xu Ying followed her mother into the Lu family after her mother remarried. She suffered all the hardships of living under someone else's roof. Worse, she became lovesick, throwing away all dignity and self-respect as she fawned over the Lu family's eldest son, Lu Chang Geng. Whenever she saw him, she could barely move. She would live and die for him, even bang her head against a wall for his sake. She made a fool of herself more times than she could count. Her reputation in the compound was terrible. To win Lu Chang Geng's favor, she volunteered to take the Lu family's daughter’s place and go to the countryside. But that wasn't what Xu Ying wanted. To her, nothing mattered more than health and money. Not even the most handsome man alive was worth suffering for. Yet she couldn't control herself, as though some invisible force were manipulating her. At first, she couldn't understand why she acted that way. Later, she learned that she was living inside a pampered-romance novel. And she was the unlucky fool who existed to help the hero and heroine get together. The hero was Lu Chang Geng, who summoned her whenever he wanted and tossed her aside just as easily. After making a fool of herself one too many times, she would ultimately lose her life because of the heroine. There was no way out and nowhere to hide. Xu Ying thought her life was over. Then Jiang Heng appeared, and everything changed. This young master from Hong Kong seemed to have a magical power: whenever he was near, Xu Ying's lovesick tendencies were effectively curbed, and she could finally give Lu Chang Geng a piece of her mind. As luck would have it, the young master fell in love with her at first sight and wanted to marry her. Without a second thought, Xu Ying dusted herself off and married into a wealthy family. But how come this clingy young master was even more lovesick than she was?
