Begonia for a Lifetime

Begonia for a Lifetime Plot:

Thirty years ago, young Lin Yan left his sweetheart Su Wanqing without a word to pursue academic studies abroad, leaving only a vague promise of "wait for me". Now gray-haired Lin Yan finally returns to the old Jiangnan courtyard, where the century-old begonia tree they planted together is still in full bloom. Su Wanqing, who has guarded the garden for decades, stands under the tree with frosted temples, trimming branches as if she never left. As petals fall on their shoulders, Lin Yan finally reveals the hidden truth: he was diagnosed with a terminal illness back then, fearing he would delay Su Wanqing's life, he chose to leave alone, using his remaining years to tend to the begonia they loved. Can this decades-long wait find its long-overdue happy ending amid the blooming begonia blossoms?
