The emotional story of a passer-by does not have a huge background story, the whole text only contains the small life of a small person. Some people play supporting roles in other people's lives, and they only play supporting roles in their own lives. They are loved but not loved, hated but loved at the same time. They can only be A, B, C and D. Even in desperate situations, we must live hard. For love, we can be as low as dust, even if flowers cannot bloom in the dust.
