For the Rest of My Life, I Wish to Grow Old with You

For the Rest of My Life, I Wish to Grow Old with You Plot:

Su Wanning, a cultural relic restorer, guards the century-old ancestral hall in the old alley—the place where she and her young lover Gu Zhao made their vow. They once carved “For the rest of our lives, we wish to grow old together” under the locust tree, but Gu Zhao vanished suddenly. Years later, Gu Zhao returns as an architect leading a renovation project, and the ancestral hall is slated for demolition. Furious at his “betrayal,” Wanning accuses him of forgetting their promise—until Gu Zhao takes out the silver hairpin he hid before leaving. It turns out he’d left to treat an illness and has been searching for her ever since. Can they resolve their misunderstanding, save the hall, and reclaim their “white hair” vow?
