In the summer of 1997, Lin Xia, a freshman at Northern Medical University, received an anonymous letter from the future at the military training base, predicting that she would die in a laboratory accident three months later. The letter warned her that she must solve the mystery of her mother's mysterious disappearance in the same laboratory twenty years ago in order to break the cycle of fate. At the same time, she was caught in a triangle whirlpool with Lu Chen, a rebellious second-generation military instructor, and Gu Mingyuan, a gentle and rational medical genius, only to discover that the fate of the three of them had been entangled due to the grudges of their parents as early as 1977 when educated youths went to the countryside.
Concept: 1. Hard-core youth and soft science fiction - a combination of 90s nostalgic elements and quantum physics concepts, military training and time travel.
