A narrative doesn't explain what's happening — it reproduces the situation as it is. That is, it doesn't tell; it shows. Unlike a straight news piece that suddenly reports a fire, a narrative reveals — through plot — the lead-up to the fire, the conflicts people went through, and so on.
In other words, by 'exposing the whole arc of an event's birth, development, climax, and resolution (or breakdown),' it builds up a visual effect — a story you watch rather than read. Like a film, a plot lets you look at characters, events, and space from multiple angles.
But what separates a narrative piece from fiction is that fiction's plot is made up, while a narrative's plot is factual. What they share, on the other hand, is that both pursue enjoyment. That's where the real value of narrative sits: delivering fact while staying compelling.
