As one would expect, the Main Character Concern is of interest only to the Main Character. This appreciation describes the area in which the Main Character is most worried or interested in regard to the way it sees the problem.

If Obtaining were the Main Character Concern, the Main Character alone would be trying to get or get rid of (hold on to or refuse to hold on to) something. None of the other characters would share this Concern because the other throughlines are all in other Classes with different Types. This divergence is what gives a story some breadth and a sense of completeness for an audience. Rather than focusing on just one issue, every point of view regarding the story’s problem falls into a different Domain with its own unique Concern.

Similarly, a Main Character with a Concern of Memory would be trying to remember, to forget, to establish a memory, or to prevent one from forming.
