Chen Yunchuan was hit by a bicycle not long after he moved to his grandfather's house. Later, he discovered that the person who hit him was actually the playmate his grandfather wanted to introduce to him.
Bai Yu knew that a child would move next door, and her grandfather asked her to play with him. She originally refused, but she didn't expect that before they formally met, she bumped into the child first, so now she could only play with him.
Intention: grow up together
