Top aerospace scientist Lin Wei, after the death of her husband, Academician Shen Huanyu, triggered the rebirth of the relic and returned to the university days of 1999. She vowed to change the fate of her lover's early death, but found that she was not the only "returner" - that young boy's eyes hid the same deep soul of the future. What's even weirder is that every time she tries to reveal the key, time will reset in a loop. An unrecognizable two-way rush unfolds quietly under the supervision of the law of time. They communicated their feelings in secret academic words that only each other could understand, and worked together in a tacit understanding on the scientific research journey, working together to fight against the hand of fate that was invisibly trying to strangle the star of China. When the shackles of the cycle finally broke when their palms touched, they looked up at the stars, this time vowing to reach the future side by side that he had reached alone.
