Just finished Spring, Summer, Asteroid, Bird. It’s a short non-fiction book about the kishōtenketsu story structure as well as nested and cyclical stories. If you read manga or light novels or watch anime, you’re already familiar with kishōtenketsu. It’s a fun, quick read. It’s informative rather than a how to. Though there is an appendix with dozens of questions that might be helpful in further cementing the concepts. Lots of great examples and spoilers abound for those examples. Well worth the read if you’re curious about the “conflict-free story structure” of East Asia.
