Title: The Darkened Heroine Is Trouble
Heroine: Xu Xingran, second daughter of the Xu family. Hero: Gu Xingcheng, rebellious eldest son of the Gu family.
They save each other.
The heroine's father was driven to his death by his enemies, her eldest brother was killed by them, her mother was driven insane, and the Xu family went bankrupt. Xu Xingran turned dark. The Xu family was no more in City A, and neither was Xu Xingran. The red rose was gone from City A, replaced by a black one. The dazzling, pearl-like Xu Xingran everyone once admired was dead. She was no longer the person she used to be. Her revenge began. Despairing of the world and of this city, she wanted to leave, but she had to avenge her family herself...
The hero: When his mother was gravely ill in the ICU, his father never once visited her. Instead, he cut off her medical expenses and found himself a mistress younger than the hero. Not long after the hero's mother died, his father brought the mistress home. With a swollen belly, the woman crossed the threshold of the Gu family home. From then on, he lost all hope in his father and came to hate him to the bone. His personality changed, too. Before long, he started a business, taking just three years to make his company the top one in City A. He was either picking a fight with his father or competing against his father's company.
They became each other's salvation. When the heroine was at her most desperate and in the deepest trouble, Gu Xingcheng appeared in her world and pulled her out of the darkness. Xu Xingran, in turn, became the only ray of light in Gu Xingcheng's world, illuminating his life.
