The evolving relationship

Ela Their suggests that you base your plots around the evolving relationship between the main character and the main supporting character:

Act 1: When a character with a pattern is faced with a problem that challenges their pattern

Act 2: Then the main character and their key relationship pursue a goal despite major obstacles

Act 3: Until they step outside of their pattern to achieve the goal and solve the problem
