"58-Year-old Liao Xinyu returned to China to inherit the family toy factory when her life was at its lowest point, and unexpectedly reunited with her first love Li Chenlang. The two discovered the time reversal device left by their grandfather, and began an adventure about youth, love and self-salvation. But as they return to their youth again and again, they must face the warning left by their grandfather: every time they go back in time, they will pay a heavy price."
Purpose: True happiness does not lie in reversing time and regaining youth, but in being able to maintain one's original intention, be brave enough to be oneself, and find one's own value and happiness in the real world no matter what stage of life one is in.
