You're conflating my real-life example of "trauma doesn't require foreshadowing" as me using my real-life example to win an argument. There's no argument to win, I'm not trying to change anyone's mind about whether this was a good narrative decision or not. If you dislike the way it was handled, that's entirely fine. It's a subjective experience after all. Personally, I really liked it and it gave me chills.
I was simply pushing back against the notion that "trauma must be foreshadowed to be effective." This manga is a great, and fairly realistic example of how someone's trauma may suddenly and visciously affect them with no build-up or explanation. I was obviously aware of my wife's trauma, so I knew where it came from. But what if she was at work? If a coworker knew nothing of her past experience (she doesn't talk about it for obvious reasons) and had an injury that caused a lot of blood and my wife had a trauma response. It would genuinely appear to come out of nowhere, and no one would say "Gosh, you could have given us a heads up..."
Fine, sure, you're "not trying to win an argument" (Although statements like "pushing back against" really undermine that claim but whatever, fine.)
But look, you're trying to paint me as the bad guy for telling you its kind of a dick move to pull out real life trauma in a
debate about the quality of a piece of writing, as though it being vaguely similar your
personal experience somehow makes it acceptable writing, and not something clumsily shoved in for some cheap drama. This is a story not real life, there are rules, a character we have followed for about 41 chapters should have more indications of being traumatized before suddenly having some sort of, quote unquote "realistic trauma attack".
Also note how many people are being snide or trying to start an argument about manga readers not being able to handle "realistic trauma" or even just "drama" That's something people like
you cause by throwing out landmines like this.
