Xu Zhiyao has been able to see the countdown of when people will leave her since childhood. Her husband Gu Yanzhou's head had a ten-year horizontal line that suddenly turned into eighty-seven days. Instead of treating the numbers as destiny, she reopened her independent life checklist, returned to her design career, founded a studio, and supported each other with her friend Tang Ning. She learned to express boundaries, reasonably negotiate family and visitation arrangements, and also encouraged Gu Yanzhou to reflect on his responsibilities. Gu Yanzhou went from ignoring his family to taking the initiative to be punctual, learning respect and commitment. Their daughter Niannian adapted to the new family structure in stable care. In the end, Xu Zhiyao understood that the countdown is just a reminder, not the answer.
