In the late 1980s, at the Birch Forest Farm in Northeast China, Lin Wanning, a returned educated youth, settled in the forest with her mother’s forestry notes. However, she was framed by her ex-boyfriend Zhou Mingyuan and his rival for "damaging rare tree species" and was about to be expelled. Just then, Gu Zhaoye, a researcher from the provincial forestry institute, appeared—he cleared her name and recognized the "natural forest protection formula" in her notes as the "unfinished paper" he’d sought for three years. It turned out Gu had been fascinated by her paper (which dared to challenge authority) and had long looked for this "fearless girl". With Gu’s support, Lin transformed from an outcast to a tech-driven forest protection leader. She exposed Zhou’s hypocritical "social-climbing dream" and, together with Gu, used formulas to protect the birch forest—while calculating their own "heartbeat formula": the best love is growing into each other’s light side by side.
