The play tells the story of a lifelong relationship between naval officer Jiang Defu and capitalist girl An Jie, showing an ordinary love spanning half a century. From black hair to white hair, under the special background of the times, the two used tolerance and understanding to resolve their differences in origin, turning trivial daily life into poetic years. The work depicts the true meaning of marriage with delicate brushstrokes - not the vigorous vows, but the mutual accommodation hidden in simple meals, and the gentle waiting hidden in the wrinkles of time. This tender narrative explains the romance of "slowly falling in love with you, and I will be you for the rest of my life".
