Vladimir Propp studied Russian fairytales and identified that there are typically 8 main character types that appear: the dispatcher, the helper, the princess/prize, the villain, the father, the donor, the false hero, and the hero. When applying Propp's theory to a short video with only two characters, some of these roles can still map to the characters but not all are needed - the male character takes on the role of the hero who tries to help the female character overcome her depression represented as the villain.
