Many of them really, I love that cunt. I love the idea of Nakayama hating being an omega because it's so annoying how people perceive him. I think he would wear the tightest collar around his neck so no one gets to smell omega scent. He hates the way the subway and office stink with so many scents mixed together. It makes him feel sick, constantly having to leave the office to smoke. The smell of cigarettes strong enough to stop him from smelling others. He also hates that he likes the smell of Shirafuji's alpha scent mixed with the smell of books and dust that the book store has.
