When Lin Yu and Jiang Xun were about to get married, Jiang Xun chose to leave this world. A year after Jiang Xun left, Lin Yu came to Jiang Xun's home. Lin Yu found a diary in her home, which recorded Jiang Xun's life trajectory from childhood to adulthood. In the diary, Jiang Xun wrote: Lin Yu, I am a person living in my world, and my world "lives" in this world, so don't be sad because of my departure, my world will always be by your side.
There is this sentence at the end of the diary: If you knew me in another world.
