profundis (novel version don’t read the manhwa its really bad)
It’s quite dark, heavy, and psychological and lwk had me staring at a wall after finishing it. Actually I couldn’t read anything else for a while after finishing it. I’m also really bummed out that they messed up the manhwa that badly. It’s a bl btw and kinda gorey.
