Knowing that Franz Kafka was a real person and Felix Kafka was made up name to alternate it. i think the classical pieces are also real, I'll come back here once I search it up.
Omg wait we have hope TT I will count on u then im not knowledgeable enough about classical music to research this TT
Hiiii, omg I found the closest one to the collections mentioned:
Idk if it's close but "Winter sea" is close to "Winter wind" by Frederick Chopin.
So I think the Etude collection she's talking about is Chopin's Etude 10 & 25 OR Scriabin: Etude Collection (Both of these collection is about toxic love/unrequited love afaik). However, the closest I could interpret for the "Beloved Opressor" is the collections of Scriabin Etudes... That's the closest I can search, I'm not saying this is right but this is the closest I can get to lmao
I'm an avid fan of classical music that's why I am genuinely looking what pieces she mentioned lol
*Winter Waves
I’ve been searching for the etude collection for so long only to realize it’s probably made up if anyone finds it please send it to me I need to hear it
