Gu Qingqing grew up in a strict family where household expenses had to be audited and approved by her elder sister, Gu Niannian. For a long time, her daily living needs often went unmet, and her living environment was far from ideal. After developing physical discomfort, she secretly went to the hospital for a check-up and learned that her physical condition was critical. However, her family failed to understand her situation, and a deep rift existed between them. On the way out one day, the already frail Gu Qingqing collapsed unexpectedly due to exhaustion, and her life came to an end. It was not until she left that her family finally woke up, wrapped in endless guilt, and began to reflect on the heavy misunderstandings and alienation in their past interactions.
