Zhang Jiajia held his wife's cold hand in front of the hospital bed and watched the monitor turn into a straight line. When he opened his eyes again, he was back in the high school classroom in 2003. The ponytail of the girl in the front row swept across his desk, with the familiar scent of angelica on the tips of her hair - that was 17-year-old Lu Xinxin. At this moment, she didn't know that the "astral syndrome" she inherited would kill her ten years later.
The reborn pharmacist took the chalk and drew on the blackboard the cellular structure that was discovered ten years later. This time, he wants to change his destiny before death: the medicinal diet cooked with morning dew contains the code to reverse the disease, the veins of the ginkgo leaves grow heartbeat patterns, and the paper cranes hidden in the desk are each filled with the secrets of future medicine.
When Lu Xinxin discovered that the boy who always stuffed her with licorice candies actually knew her family's medicine, and when the fluorescent jasmine in the biology laboratory bloomed into a heart shape at midnight, the secrets hidden deep in the traditional Chinese medicine cabinet gradually emerged. Zhang Jiajia must race against time to prevent the black hands of transnational medical organizations from reaching the campus before curing the pale gold veins that appear on the girl's body.
"If it takes time to cure you," he put the stethoscope on the girl's heart, "then I would like to be your exclusive doctor forever." This time, he not only wanted to cure Lu Xinxin's illness, but also repaired the youthful throbbing that he had missed in those years - at the moment when the medicine resonated with the heartbeat, he had a first love that spanned life and death.
