Twenty years ago, Liu Yuchuang agreed to a dying friend's final wish to raise his daughter, Liu Wei, alone. To provide her with a stable life, he gave up an easy job and sold roasted sweet potatoes from a street stall for twenty years without remarrying, yet he was despised by the grown Liu Wei for his poverty and disability. Obsessed with vanity, she lied that her father was a wealthy overseas boss, hooked up with the rich second-generation heir Chen Hao, sneered at Liu Yuchuang's blood, sweat, and care, and even publicly denied their father-daughter relationship. It was not until her father passed away that Liu Wei opened his sealed diary and photos, realizing that this man with no blood relation had spent twenty years in endurance and deep love!
