Okay kiddo, so we're going to talk about something called "mythos" which was a really important idea to a guy named Aristotle a long time ago.
Now, imagine that you're watching a really good story. Maybe it's a movie or a TV show or even just someone telling you a bedtime story. You get really into it, right? You care about what happens to the characters and you want to know how it all ends.
That whole story with all the characters and the plot and everything is the "mythos." Aristotle believed that having a really well-written mythos was super important for making a story worth caring about.
He said that a good mythos needed to have certain things, like a beginning, middle, and end, and that the characters should all be connected in some way. That way, you can see how they all affect each other and how the story unfolds.
Basically, mythos is the heart of a story - it's what makes you care about what happens next. And if a story doesn't have a good mythos, well, it might not even be worth telling.
