Jiang Wanxing became Shen Yehan's secretary incognito, secretly stealing business secrets for revenge. Shen Yehan had already seen through Qu's plan and played with her in the business war. The two were apparently superiors and subordinates, secretly enemies of life and death, but they had a drunken relationship and have been entangled ever since. Jiang Wanxing teamed up with the Shen family's business rivals to make a plan, and Shen Yehan used her plan to annihilate the enemy in one fell swoop. Jiang Wanxing failed in revenge and fell into despair. At this time, the truth emerged - the bankruptcy of the Jiang family was framed by Shen Yehan's half-brother and external forces. Shen's father was also killed in that conspiracy. Shen Yehan has been secretly investigating for these years. The two turned from enemies into allies and joined forces for revenge. In the end, the mastermind behind the scenes was defeated, the fathers of both parties were vindicated, and the old feud was cleared. Shen Yehan proposes to Jiang Wanxing, and the two families marry to resolve generations of grudges.
