Su Yin returns from overseas and inherits the shares of the Su Group. However, her stepmother An Ruxue unites with the chaebols and aristocratic families to force her to marry. The lawyer and the Su family's son-in-law are also bribed by her to seize the family property. Su Yin flatly objected, and the most handsome Ye Xuanyi caught on the street had a flash marriage to temporarily resolve the share crisis. She went home and declared war on her stepmother. Although she was poisoned, disrupted by the board of directors and other plots, she was able to resolve them without any danger. What surprised Su Yin even more was that his "brother-in-law" Ye Xuanyi actually hid a secret and had been waiting for him. Faced with his concealment and stepmother's oppression, how should Su Yin make a choice?
