Chao Le and Mu Gui were childhood friends, but Mu Gui fell in love with Chao Le because of Chao Le's words when he was a child: "I will marry you when I grow up."
But Chaole went to school in another place for some reasons, and when they met again, he was a boy taller than Mu Gui. Mu Gui was very excited to see Chao Le. But after being teased by both parents, Chaole said, "It was just a childhood joke and should not be taken seriously."
Mu Gui went out for a walk because he was sad, and met Chao Le who was looking for him. Mu Gui forcefully kissed Chao Le in the park and asked him if he wanted to be together, but Chao Le refused. But the future life of Chao Le and Mu Gui are still ambiguous.
It wasn't until later that I found out the reason. Chaole had always liked Mugui. After understanding the reason, the two got together, and both father and daughter agreed.
Purpose: The promise of love also needs to be taken seriously
