Trigger warnings (also known as TW), are put in the beginning of chapters to forewarn the audience of sensitive subjects that may come up, such as suicide or rape. There is a big controversy of whether trigger warnings are real for people or not, but to just be on the safe side and not get yelled at PLEASE put them there. I'm not asking for a war in the comments section, either. PLEASE put them at the beginning of a chapter if topics like those ever come up!
