A faded letter under a green tile in Jiangnan reveals the half-life entanglement between grandmother Shen Qingwan and the mysterious man Su Muan.
When Lin Wan returned to the small northern town with her grandmother's last wish, the yellowed diary, dusty old things, and the old man's vague memories pieced together the war-torn era - the encounter between a rich businessman's daughter and a poor scholar, the forced separation due to family obstruction, and the silent watch half a century after their marriage.
Grandfather Lin Zhongming's tolerant love throughout his life, Su Mu'an's obsession with never marrying until death, Shen Qingwan's pursuit across thousands of miles in her later years... The emotional bonds of three generations are intertwined in the river of time.
"If I had been braver, would the outcome have been different?"
When the pieces of the truth were finally pieced together, Lin Wan not only found the answer to her ancestors, but also untied the knot in her own heart.
This is a story about love, regret, and reconciliation, as well as an elegy to the old days.
