Against the Current, Back to 1999

Ji Yao: A 35-year-old finance professional in her previous life, she was killed in a staged car accident for investigating the "Dark River" financial fraud case. Reborn in 1999 at age 18, during the final stretch of her senior year of high school. Her goals: save her mother, take revenge, get ahead of the future, and protect Lu Ziming. Core strengths: financial and technological insight twenty years ahead of its time, a resilient mind, and a keen sense of danger that grows stronger over time.

Lu Ziming: A future tech magnate in the making, a gifted science student at the same high school in his senior year. Introverted and focused, he had his core algorithm stolen in his previous life, leaving his ambitions unfulfilled. This life takes a different turn after Ji Yao steps in. Core strengths: exceptional mathematical and physical intuition, programming talent, and a passion for hardware.
