So we finally wee that Grenouille is making the human sceented perfume we read about before, but he is only making it to mask the human scent that he lacks. His only goal with this was to smell like everyone else does. He wants to use the perfume for this reason now, but eventually wants to make a similar perfume to make everyone in the world love him.
I looked up human scented perfumes and it turns out there is something called a pheromone. It is a chemical secretion that effects the behavior of another person or animal..generally sexually. http://abcnews.go.com/2020/Health/story?id=1386825 This news story says that there are perfumes being made that are used specifically to draw in a partner and because this attraction is genetic, as long as it is compatible with the other person, it should work. It is super creepy. I’m okay with this happening naturally, but making a perfume that tricks you is super weird! I feel like this is exactly what Grenouille is going for. He just want a perfume that will attract other people to him and that is going to make the book weird.
