If you want to highlight the character's arc or hide the foreshadowing, you can also adjust the presentation, such as strengthening Chen Mo's transformation from passive acceptance to active inheritance of hope, or adding some hints to Lin Xia as to whether her father's clues are hidden, so that the introduction can better fit the key points of the story you want to highlight~
