Where is my husband created a topic of Corpse Party

I remember watching this anime 10 years ago, at first I thought it was just like normal student animes not reading the genres properly.
Throught out the series, I got a lot of trauma (I was only 11 at that time), the characters I had a crush on died one after another, but still I cant stop myself from watching it hoping that was nightmare and they will meet each other again
the end was tragic for me and still can't accept the ending

I saw some some spolier that this is going to be end up in harem
there is one thing I don't like
why did the author made so many sexual assaults ? and why did they made it seems like Lux is the Male lead so far?
there are many who are shipping for lux and FL but still it is hurt to see fl with another MLs being SA by them
