So I don't consider myself an angst reader so even my most gut wrenching reads may feel soft for you but I'll try to at least give genuinely good reads imo

Preferably after reading the abused pov because I liked that experience better

This affected me the most because of my religious background... It felt closer to reality and I did not live that well

Mostly disgusted... Not necessary sad. Will not elaborate.

Just check the author OF FUCKING COURSE THAT ENDING WAS THAT. I cannot justify why I liked this uncomfortable read but for me it was well built

Not that emotional at all lol... But it's yakuza with standard yakuza backstory... I personally enjoyed reading the chaps in random order

Not the best, kind of uncomfortable read

Oneshot, fucked up, needs a longer version maybe (eithercase I'd read more chaps on it)

I don't remember much now but I did put it in my "let's appreciate the commitment" list so...

Copy paste of a comment cuz it was perfect depiction: "I wondered how 2 chapters could solifidy something like amnesia without being too easy. I didn't expect something so deep and so world shattering in just 2 chapters. Shit, that trauma drawn in a few panels was enough to break me. Aaahhhh!"

I remember liking and feeling overwhelmed about the depiction of multiple personalities disorder

I had a convo with my hallucinatory therapist, ik it's pretty known too
I think that all I can offer, hopefully at least one fits your taste
Someone pls give me the most gut wrenching thing to read and preferably short as in under 10ch up over that is fine too
