Yeah im not in the loop either but all im saying is there is already an example of what many would consider a "life changing event" and it has the same importance (in story) as any other random hangout that leads to sex
and as others have said there is a huge difference between stuff like drama/story needing conflicts etc (even something as serious as raping your best friend) and a character literally dying...even ignoring how anyone feels about the character in particular what about people in the future? All they need to do is look up their name (or use walkthrough, or talk to someone who has played up to that point, or noticed that she has less fan art/sigs/whatever) to know that she dies.....and are you really going to use time (in game and irl) to see scenes or care about someone who dies a considerable amount before the game ends? Then some (not half lol) will leave because someone they liked died, with even more leaving because
AN LI DYING (STAYING DEAD) WITHOUT PLAYER INPUT HAS NEVER WORKED IN AN AVN (debatable if you consider someone dying in the prologue as the crux of the story)
