Honestly, for me it was metamorphosis. Metamorphosis is a short story made by Kafka. It really showed how if a person is useless then people just discard them. How the family of the mc just threw him out because he couldn’t work or provided. It was so true that people would actually do that, even your family members that it made me cry.
Recently started a book series referred to as the Murderbot Diaries where the protagonist is essentially a cyborg that hates humans, is socially awkward, and just wants to be left alone to watch media and I’ve never related to a character so hard!
