6 Summary
In future studies, I will raise the number of authors I examine. I will form an impression of north, south, east, and west or Olympic in consideration of the balance of global scale. If I could link not only different romans of an author but also different authors by compiling databases, the synergic metaphor could improve my analytical ability, because through it, I could see the unexpected thing. When I study literature at the macro level, the global scale and the shift of format become necessary and sufficient conditions.
