Lin Zhixu and Zhou Muye grew up as neighbors on opposite sides of the alley. From competing for candy to competing for school district housing, from comparing grades to annual salary, they are each other's most familiar "enemies." During urban reconstruction, the alley was to be demolished, and two families turned against each other over the compensation. They were forced to cooperate. In the last three months before the demolition, they discovered the grievances between the two families and the truth about the child exchange that had been deliberately hidden - one of them was not biological.
Concept: Familiar strangers, urban renewal of identity and belonging, the intertwined bonds of love and hate
