On a rainy night at the age of thirty, Lin Xiaowei ended her marriage. In the empty study room, an old pocket watch engraved with a star map pulled her back to 1998 - the seventeen-year-old who was once blind for love.
This time, she tore up the love letter she wrote to her first love and wrote "Tsinghua" on the test paper. The mysterious pocket watch quietly changes the star map with her choices, and the Lu Yuanzhou who will become her husband in the future is still an alienated genius boy in the competition class.
Star tokens spanning time and space, the unfinished astronomical dreams of her parents, ancient constellations with hidden mysteries... Lin Xiaowei gradually discovered on the way to pursue her dreams: the pocket watch not only connects the past and the future, but also two hearts that have been destined for a long time.
When the countdown second hand turns again, can she hold on to the starlight and rewrite each other's life trajectories?
"This time, catch the light."
