Dramality is like when you're watching a TV show that has some parts that are real, and some parts that are made up to be more exciting. It's kind of like a mix between drama (which means something that is really interesting and exciting) and reality (which means something that is actually happening in real life).
So imagine you're watching a show about people running a restaurant. Some parts of the show might be real, like when they actually show the chefs cooking the food and the customers eating it. But some parts might be made up to make the show more interesting, like when the chefs argue or there's a big problem with the restaurant that they have to fix.
Basically, dramality is a way to make a TV show more interesting by combining real-life situations with some added drama. But it's important to remember that not everything you see on TV is always 100% true, and sometimes things are added just to make the show more exciting.
