Here is our character chart for My Country which is what we use to remember who each person is, what their initials are, and what their characters title/job is. I go back and forth between using names, initials, or job titles depending on how fast I’m typing or if it seems like a paragraph is turning into character soup.
The Character chart can be kind of spoilery at times because we go by character descriptions from the website while creating it. So someone might be called King on the character chart and they are not actually King yet in episode 1 or 2. But we don’t know how quickly or late something will be revealed, so we just include it to better understand the storyline ourselves.
