Song Mingyuan, a 42-year-old real estate agent, finally got married to Fang Qing, a single mother who has been in love for many years. However, the wedding was only a hundred days old when a sudden car accident took away Fang Qing's life. Before Song Mingyuan could get over the pain of losing his wife, he was told that he had become the temporary guardian of two children - the 17-year-old problematic girl Fang Tang and the six-year-old naughty boy Fang Doudou.
He could have chosen to turn around and leave, but looking at the blank eyes of his two children, he remembered the unfinished words of his wife before she died. The late wife's ex-husband Zhou Haonan also came to the door at this time, demanding to regain custody as her biological father. Song Mingyuan was pushed to the forefront by fate, and a battle about love and responsibility began.
