Jiang Chu transmigrated into a female-centric novel and became the male lead's materialistic ex-girlfriend.
According to the original novel, the female lead, who comes from the Xie family, the most powerful financial group in Beijing, will use her power and cunning to bewitch the male lead.

Jiang Chu, dressed in a haute couture gown, walked slowly down the stairs arm in arm with the man, her diamond ring sparkling like stars.
She looked at the original female lead, who was completely shocked, and smiled slightly, "My good daughter, why don't you call me Mom?"
