The meaning of this sentence was: Every story needed an ending, but without an ending, it was called life. This quote was from the novel "You and I are the only one missing", which told a story about pursuing dreams and love. Life, like every story, had a beginning and an end, but life did not have a fixed ending like a story. Life is full of unknowns and changes. We are constantly experiencing all kinds of things, growing and improving, and this change and growth does not always end in a fixed way. Therefore, life is a story without an ending, and we need to constantly explore and experience it.
