I can see you are prime relationship material. Dude, you are seriously going to discuss religion here? What is wrong with you?
...takeing metaphors isn't your pair of shoes I take it...
But some of your Posts actually raise the impression you brought religious matter into this thread long before me.
Getting back to the toppic though...
I am unsure why people fight against the "Harem" route that much... as far as I remember the player is never forced to follow any other persons route than the one he likes... the main story is about the player getting revenge for being humilated (and what we learn about the teacher she is the bad guy in this story)... the player might take it to far with her... but honestly if you don't take this stuff into RL it's just funny
