The heroine Su Wan (codenamed "Qingcha"), in order to investigate the truth of the "Hidden Reef" operation that led to the destruction of her family ten years ago, uses her identity as a tea artist as a cover to proactively approach and intend to infiltrate the "Panshi Group", a gray business empire controlled by the vengeful villain Huo Jun. Her primary target is Lu Chen, the group's security consultant and a retired soldier with a mysterious identity. In the process of testing, cooperating and confronting each other, the two moved from suspicion to trust. Su Wan used his excellent psychological profiling and micro-expression analysis skills (not Golden Finger, but his special forces training background) to break down Huo Jun's psychological defenses time and again in seemingly elegant tea ceremony games, revealing the truth about his crimes in the name of "revenge", and gradually pieced together the shocking secrets of his family's murder and his own life experience. In the end, she and Lu Chen cooperated inside and outside, not only uprooting Huo Jun and his protective umbrella, but also completed the redemption and return of her own identity.
