This is a work focusing on family emotions: Young couple Mark and Lena gradually fall into a marital crisis (even considering divorce) due to life pressures and communication gaps. Their son Tim, who is sensitive to the changes in his parents’ relationship, tries his best to reconcile them in his own way (such as planning family activities and secretly conveying each other’s intentions) to save the family. With Tim’s "help", Mark and Lena look back on their relationship, face the conflicts in their marriage, and finally, through the child’s innocence and persistence, rediscover their attachment to the family and choose to repair their relationship together.
