The heroine, Qin Hongyao, is naturally beautiful, cheerful, and exceptionally clever. She is the top student and campus belle of Ancheng No. 1 High School, yet she is forced to marry Zhu Banqiao, a disabled man five years older than her. The reason is that Zhu Banqiao’s father saved her own father, Qin Lie, during a rescue operation years ago. Out of gratitude, Qin Lie arranged their marriage when they were children to repay the life-saving debt. It was supposed to be her older sister, Qin Hongtu, who married him, but she flatly refused. Wanting to repay her parents for raising her, Qin Hongyao impulsively volunteered in her sister’s place. She never expected this to open Pandora’s box and send her tumbling into a bottomless abyss of endless darkness.
