Lets go back to the original example made in
>>17020
"What do kappa want out of life?"
Lets answer the questions I proposed in
>>17032. What is the problem, who is solving the problem, and how is the problem solved?
"What do kappa want out of life" rephrased in the form of a problem would be, "a kappa does not know what she wants out of life" or "a kappa is dissatisfied with her life."
Problem: a kappa is dissatisfied with her life
who is solving the problem: a kappa (I'm going to say Nitori)
How is the problem solved:
>>17033's suggestion is as good as any for now. A kappa goes to market one day
We now have a basic plot summary. But if we want a thematic summary of the story, we need to ask a fourth question: Why? Why is this a problem? Why is this character solving the problem? Why is this how the character is solving the problem?
Problem: a kappa is dissatisfied with her life
-Why is this a problem: The kappa saw several other kappa couples while she was out walking, and she is now lonely because she is still single
Who is solving the problem: Nitori
-Why is this character solving the problem: Nitori is tired of being single and doesn't want to die alone
How is the problem solved: A kappa goes to market one day
-Why is this how the problem is solved: There is a cute kappa that works at the market and Nitori wants to ask them out.
Thematically I have just created a romance story. But lets try this exercise again.
Problem: a kappa is dissatisfied with her life
-Why is this a problem: Because the kappa tripped and landed face first into the pie she was carrying
Who is solving the problem: Nitori
-Why is this character solving the problem: Nitori is embarrassed because she made a fool of herself in front of a crowd of people and got laughed at.
How is the problem solved: A kappa goes to market one day
-Why is this how the problem is solved: Nitori bought all the pies in the market so she could throw pies in everyone else's faces to make herself less embarrassed.
We started with the exact same plot summary, but this time the story is thematically a slapstick comedy.
Problem: a kappa is dissatisfied with her life
-Why is this a problem: the kappa's mother died recently and now she is faced with the reality of her own mortality
Who is solving the problem: Nitori
-Why is this character solving the problem: Nitori saw that her kappa friend was depressed by their mother's recent death and wants to help her friend out of their slump
--But why is that important: They have been friends since they were kids, and seeing that her friend is hurting makes Nitori hurt too.
How is the problem solved: A kappa goes to market one day
-Why is this how the problem is solved: The kappa's mother used to buy the kappa ice cream from this market when they were sad as a kid,
--But why is that important: Buying some ice cream now makes the kappa realize that their mother is not truly gone, and their friend Nitori is still there to make life worth enjoying.
Now its a heartwarming drama about loss and friendship. I didn't get enough of a grasp on the thematic beats of my story the first time, so I asked "why" again to make the direction I want to go in clearer.
Asking "why" can help you figure out what sort of themes you want your story to have, can help you make sense of your plot, and can help steer your story in the thematic direction you want it to go in.
