Ji Li and Li Mi are neighbors. They have often caused trouble together since they were little. They have always taken turns taking the blame, and their relationship has grown deeper and deeper unknowingly. Just like brothers and sisters, when Ji Li chases a girl, Li Mi will help him. When Li Mi chases her Tang Monk on a White Horse, Ji Li will make suggestions. However, the two of them have different circles of friends. What kind of sparks collide and what kind of upheavals happen in their respective circles of friends has always been a generation gap between the two.
Later, they understood through tears that some people are no longer there if they miss them.
