Three years ago, an accident forced Su Qinghuan to shoulder the responsibility of mother alone. In the old house on Wutong Lane, she carefully guarded her daughter Su Nian'an and lived a plain but stable life.
The sudden appearance of Gu Yanci broke the tranquility. This man who had left a blank space in her life announced with belated apology and determination that he would intervene in their lives - he was Nian Nian's father.
One is a stubborn mother who raised her children alone and has grudges about the past; the other is a stern CEO who is trying to make up for his three-year absence and wants to take on the responsibilities of a father; plus an eccentric cute baby Su Nian'an who becomes the "glue" between the two, and the fate of the three is closely intertwined.
From the initial resistance and temptation, to the friction and tenderness in getting along, Su Qinghuan gradually discovered the softness hidden under the indifference of Gu Yanci, and Gu Yanci also learned how to be a qualified father and partner in their company. And Xiao Niannian uses a childish perspective to dissolve the barriers in the adult world little by little, allowing this reassembled "home" to slowly gain warmth amidst the stumbling blocks.
