[Fan Fiction] Synopsis: Hao Huigui is a 37-year-old unmarried university teacher. At a gathering, unable to stand how his old friends had become slick and worldly, Hao Huigui argued with every one of them and even got into a vicious fight with his best friend. After returning home, he got drunk and accidentally opened the diary he had kept 20 years ago. Remembering many things from the past and seeing his younger self’s hopes for a bright future, he was overcome with guilt. As he read, Hao Huigui fell asleep and had a long talk in a dream with his younger self. While reading his old diaries, he gradually came to understand another side of events from the past that he had forgotten. He realized that instead of running away and complaining, true growth comes from treasuring what you have, and facing your regrets and difficulties head-on. When he woke up, Hao Huigui realized that although he could not change the past, he could change who he was in the present. He closed the diary, determined to start pursuing his dreams bravely from that moment on, so he would not let down his younger self. In the end, he reconciled with his friends and bravely confessed his feelings to the woman he loved.
