Su Wan, a Harvard MBA and former strategic consultant at BCG, could have been making waves in the consulting industry with an annual salary of one million. But she chose to return to China and join Shengtong Group as an intern - a company founded by her mother but usurped by traitors. She has only one purpose: to find out the truth behind her mother's death in a car accident seventeen years ago.
No one knows her true identity. In the company, she was regarded as the "tea girl" who served tea and water. She was bossed around by her colleagues and made things difficult for her by her boss. But she doesn't care, because she's not here for promotion and salary increase, but for revenge.
However, plans cannot keep up with changes. The aloof CEO Gu Shen who handed her a cup of coffee in the elevator always appeared in her sight inadvertently. He helped her block knives, helped her investigate cases, and helped her solve one problem after another, but he never took credit. Su Wan found that her heart was sinking little by little.
As the investigation deepens, a conspiracy spanning two decades gradually emerges - the mother's death was not an accident, but a well-planned murder. The masterminds behind the scenes include not only company veterans, but also Hong Kong money laundering groups and large families colluding with politics and business. Even Su Wan's own life experience has been completely overturned.
From intern to chairman, from rookie to business queen, Su Wan made comebacks in desperate situations. And behind her, the man who had always been silently guarding finally waited for her response.
