if you scroll down in comments there are people who have read the novel and wrote down the proper spoilers.
I didn’t read the novel but tldr (from comments): this should get more fucked up based on flashback lore. Kidnapper was gang raped by kidnapee as a child, the gang rape was filmed and distributed, the woman in the hospital is kidnapper’s mother that mentally broke from seeing the video (?), kidnapee doesn’t remember bc he got into a fight later and got amnesia. the revenge torture gets more fucked up

Does it get better or does it just get more fucked up please spoil me bro I can’t take tis
