After five years of painstaking work, physics prodigy Ning Yuan finally completes an epoch-making invention: the Anchor of Time. But during its first experiment, an accident hurls him back twenty years, to a rainy night where he watches a car careening out of control toward a young college student, Su Yuqing.
A cruel truth comes to light: in the original timeline, Su Yuqing was supposed to die in this very accident. And she is the woman Ning Yuan would one day love more than anyone, his future wife.
Ning Yuan faces the most difficult scientific and ethical choice of his life:
Should he obey the law of conservation of spacetime and let fate run its course?
Or break the laws of physics and save the girl destined to fall in love with him?
"If saving you means forgetting you, would you still be willing to meet me again?"
When a scientist hits the reset button for love, will spacetime punish him, or will fate give him a second chance?
