"A Negative Makes a Positive" is a youth fantasy novel that revolves around the exchange of consciousness in parallel time and space. The story is set in two parallel time and spaces that are like mirror images. When the cheerful Lin Yi and the quiet and introverted Su Wan in the first time and "self" with opposite personalities in the second time and space resonate emotionally at the same time on a thunderstorm night, their consciousnesses are permanently exchanged, starting a profound exploration of identity, love and destiny.
After the exchange, the two were forced to live as each other: Lin Yi became a calm academic master, while Su Wan had to play the role of a energetic girl. They met secretly in the "mirror space" through the medium of ancient coins and supported each other. However, in the process of adapting to their new identities, they found that their entanglement with the original owner's consciousness became increasingly complicated - the original owner's consciousness did not disappear, but entered their bodies, forming a closed loop in which the four people's consciousnesses intertwined and coexisted. As the energy of the ancient coins fluctuates and the rules of time and space emerge, they try to find a way to return, but the butterfly effect is triggered repeatedly, causing family, friendship and love to fall into multiple crises.
The story deeply explores the core proposition of "what is the true self when the body and soul are separated". Through a two-line parallel narrative and a mirror-symmetry structure, the novel depicts the characters' struggle for identity, resistance to the uncertainty of fate, and affectionate protection across time and space in the intersection of time and space. In the end, when tragedy strikes, the four have to make a choice between sacrifice and fulfillment, trying to break the fate of reincarnation and find their true destination.
