As a person who has been through some shit myself, I say to you, don’t read it. It’s obvious you’re still healing from whatever you went through but no one is making you read it. The author chose this plot, as old and overdone in this story, it is how this story plays out. In the future, just drop stories that trigger. It makes no sense reliving past trauma for the sake of reading any genre of manga. I hope you feel better soon.

I have it too. You gotta be careful with it. I went to a shooting range with a friend to get over one of my anxieties. I was fine with shooting and with him shooting because I was coaching him but not knowing there was someone else at the other end of the range shooting scared the crap out of me when they fired. Every shot fired, I felt. I had to concentrate on my own shooting to try and block it out.
Stick to manga for now. Webtoons from Korea and China are severely violent. There is no way you wouldn’t get triggered. Try Acid Town.
I am about done with this series. Enough is enough. The constant abuse both sexual and physical is just disgusting and I really don't care if it's an unpopular opinion, but I can share mine same as anyone else. There's just so much I can stomache and it hurts to see this being a constant theme. I am not a snowflake, just someone that's been through both these situations myself and it hurts to see no one helping this poor guy. Reminds me too much of myself and it took too long for me to piece myself together and I consider myself a tough and compassionate person. I just don't need this much toxicology.
