Chuanchuan and Yangyang.

Taxi driver Wang Dong and his wife divorced and took their son Wang Guchuan (Chuan Chuan) with them, and Shen Fang, who also divorced and took their son Liu Yang (Yang Yang), formed a new family. The older Chuanchuan is in adolescence and has a rebellious character, and firmly opposes his father's decision. On the contrary, the younger Yangyang is cute and sensible, and understands his mother's remarriage. Helplessly, God plays tricks on people. Wang Dong and Shen Fang, who were originally full of confidence in their new life, unfortunately died in a car accident, leaving behind the two brothers Chuanchuan and Yangyang who were full of conflicts.
