Retired German professor Chen Lan concealed her identity and worked as a housewife for ten years in order to take care of her son Jiang Wei's family. However, she received contempt from her daughter-in-law and granddaughter and indifference from her son. After being insulted in German by her granddaughter, she finally woke up, regained her identity and assets, decisively cut off from her original family that consumed her, and returned to the academic field to find herself. Faced with her repentant granddaughter, she chose to give her a chance, guide her growth with wisdom and tolerance, and ultimately lived a calm and confident life.
