Six-year-old Fu Nianyun found a dusty diary in his father's study. On the title page was the handwriting of his mother Wen Zhiyunjuanxiu: "For those who know how to love." In the diary, the sunny and tenacious Wen Zhiyun recorded her embarrassing first encounter with the "Iceberg Boss" Fu Si - she poured coffee on his expensive suit, but was captured by the "silent lake water" in his eyes. She vividly depicts heart-warming moments, clumsy dates and sweet love, with vigorous vitality jumping between the lines.
Holding his daughter in his arms, Fu Si used a gentle and deep voice to fill in the blanks outside the diary: how the "little sun" from his perspective that crashed into his dark world soothed his anxiety in a strange way; how he "quietly" created chance encounters; his deep-seated guilt of neglecting his pregnant wife because of work. Through the intertwined memories of her parents, little Niannian came into contact with an unforgettable love.
When the diary turned to the last words Wen Zhiyun wrote weakly before his death, the father and daughter hugged each other tightly in tears. That diary is no longer a relic, but a messenger spanning life and death. In the end, Fu Si stood in front of the grave holding Nian Nian in her hair with a sunflower hairpin made by her mother. Nian Nian raised her head and whispered to the stars: "Mom, dad and I are both fine." The sun shone on Fu Si's relieved smile and Nian Nian's mother-like smile - they held each other's hands and walked towards a hopeful tomorrow with the eternal love of the deceased.
