Due to a temporary business trip, Xu Jiayan had no choice but to entrust his socially fearful daughter to his ex-husband, the cold-faced instructor He Wei. He was worried at first, but found that He Wei took good care of his daughter with the meticulousness and clumsiness of a soldier, and regarded her instructions as a battle plan. Xu Jiayan discovered many clues while getting along, and later learned that He Weiti's divorce was due to his helplessness in protecting her while performing an undercover mission. The misunderstanding was resolved, and with their daughter's bond, the two regained their love, remarried and became a happy family.
