Most narratives have two or more clues. For example, Mr. Fujino, the article has both the communication between the author and Mr. Fujino as a narrative clue (bright line) and the dark line of the author's patriotic thoughts and feelings.
The order of narration requires mastering three kinds: direct narration, flashback and insertion. Sequential narration is written in the order of occurrence, development and ending, and the cause and effect are very clear.
