@hamster91 well I haven't been raped but I have had a gun intentionally pointed at me and had injuries as a result so I would say that the attempted murder in the chapter would hit home more to people like me. I'm not unsympathetic to rape victims (my wife suffered it and even dealing with it second hand could be trying) but when we start giving out warnings for strong emotional events that effectively destroy the plot of a chapter before you even begin reading it impacts any drama to a degree since you already know were its leading to.
@Squidco42 Actually we only see her being chased and cornered, the rest is implied as well. The "murder" events cover a number of pages as well. I would argue that if suggested rape is worth the effort of a warning for a "fluff" manga then attempted murder should be as well. Obvious from my comments I'm not a fan of any trigger warnings, its simply pandering to a particular set of weak minded individuals who can't differentiate reality from fiction at the price of ruining the plot details for the majority of us that can. If the attempt rape or attempt murder doesn't get your blood rushing then the author isn't doing a very good job because that is what "drama" is, warnings or not.
@icekatze No, people don't come to terms with eventual death, they simply don't focus on it in most daily normal life. Believe me, once you are faced with yours or a close persons potential of immediate death it changes your perspective at that time. No more than you wake up thinking "today I could be raped" do we wake up think "I could die today" (unless you are living with a terminal illness like cancer). Believe me in my personal experience whether it by gun, illness. or other, you do move on.
