Lin Wanxing, a genius perfumer with "hyperamnesia", can remember the smell, sound and picture of every second of his life. This talent is the cornerstone of her career, but it is also an emotional shackles for her - she can never forget every detail of her lover Lu Ziang's death in the car accident that changed her life seven years ago. In order to find an outlet for forgetfulness, she invested in the research and development of a nerve healing perfume called "Tracing the Origin". However, when she was closest to success, a neurologist named Gu Huai broke into her world with an aura highly similar to Lu Ziang's. The appearance of Gu Huai not only disrupted her research and development rhythm, but also caused cracks to appear in her dusty memory. Is it a coincidence or a well-planned puzzle? When the memory of "hyperamnesia" collided with the cruel truth, and when unforgettable love intertwined with long-planned protection, Lin Wanxing discovered that what she desperately wanted to forget might be what others wanted her to remember with their lives. In this battle between memory and forgetfulness, who is her ultimate salvation?
