Even though Ning Ran had lived for 17 years, he never thought that he was not the biological child of the Ning family. All of this stemmed from an unexpected incident. I thought that after the exchange between the two families came back, it would be a bridge back to the bridge, but I didn't expect that the disconnection would continue.
The other protagonist of the story, Lin Yucheng, is the eldest son who was supposed to be born into the Ning family with a silver spoon in his mouth, but he does not feel that the 17 years he has lived in the Lin family have made him feel wronged.
