Sonoko's love letter analysis

I think someone people watching would be dumbfounded by Sonoko's letter, so I decided to write a note to help people understand it. Please note that I don't study literary, and so I may not be able to catch all the subtleness, but I at least know enough to let you know the main idea. If any of you have a major in literary, maybe you can add on this. Also, this is a half-ass interpretation. I hope no one else will try to copy this style.

There are many keywords in this prose. Whirlwind, spiraling melody. These imply the chaos she is experiencing. Nebulous means "hazy", "fog". It means the feeling is unclear. Multitude of stars would imply the massive size of the chaos.

Then Tougou line basically means that the feeling overwhelm the empty her, who has always feel empty before meeting him.
Hinata and Chikage amplify it further.
Sonoko mentioned Dionysus. Dionysus is known as the god of wine, but also known as the god of insanity. the abyss that is Dionysus's alluring smile would be the invitation to the abyss of insanity, as foreshadowed in the previous part.

I have no idea what "primeval heart" means :sweat_smile:
