One of the way the Functions of dramatis personae discovered by Vladimir Propp to be interpreted

The name of Vladimir Propp and the title of his book "Morphology of the folktale" both are well-known in the world, not for only the literary specialists, today. Many scholars try to find the Functions of dramatis personae in various writings or films, we can see it during watching videos on YouTube or reading science articles (both the ways are equal in my opinion). But what they actually mean, those "Functions of dramatis personae" (I have found the concept of "Functions of Propp" once as well)? Okey, not actually but in general. In this paper I am showing one of the way to answer the question.
