The oldest son and daughter of Liu Jinqing were already married and looking forward to enjoying their golden years. However, at the 70th birthday celebration, they tragically passed away due to a heated dispute between the siblings. Liu Jinqing now faces challenges in determining the validity of wills, pre-existing debts, and the presence of an unregistered wife named Zhang Changlan. This situation has led to significant changes in the lives of the three children and their families. The eldest brother, Liu Yi, is reserved, straightforward, and lacks the assertiveness needed to take charge. His younger brother, Liu Fan, is gentle, patient, and somewhat timid, often putting his own needs aside for his wife. In contrast, Liu Xiong, known for his kindness, resourcefulness, and energy, has been thrust into a leadership role, taking on the responsibility of resolving the escalating family conflicts. These complex dynamics have opened a new chapter in their lives.
