I have one MC that will discover more about themselves, and in that, they will discover the different parts of themselves — their psychology and their hidden desires. The deeper the person, the more different parts/people that will show about themselves, but they are not the only one who will be doing that. Other characters will discover themselves and their own psychology.
Now here's the thing, each of those "different parts" are presented as the character, but with a similar or different designs. I am not sure if I want them to be considered as "characters" since it will make the cast too big. Maybe I shouldn't make them as characters or simply just erase the other characters and let the MC be the only one experiencing this.
