I'm not proud to have finished this story and I wouldn't recommend it to anyone.
It's highly disturbing and contains torture, murder, rape, gore, psychological terror and everything that counts as a red flag.
I started reading because it was on my recommended yaoi list.
The art style is good and it kept me hooked for a while.
When you realize that the protagonist is falling deeper and deeper into the darkness you pity them and hope for salvation. Every further chapter feels like a needle poking under your skin. You keep searching for the humanity among the inhumane. It makes you feel horrible and disgusted by yourself for not being able to stop reading. Since that was the intention of the author, they did a job well done here.
From a personal perspective, I don't want to read anything like this again.
