Any book recommendations like No Longer Human?

No longer human is truly unique. The only other book I would consider kinda similair is kokoro by nataume soseki

Kafka on the Shore by Murakami
Confessions of a Mask by Mishima

Had to read this for school but:
Woman at Point Zero by Saadawi
It made me think a lot. Definitely not something you can read in one sitting due to the heavy themes imo

Maybe Rashomon
Or Discourse on Decadence
Definitely didn't know them becuz of BSD
