Since a while we know that teh relationship between Akemi and Itome is not an easy one. I think Akemi was very in love with the black hair guy and I think they were boyfriends and for what we know now, the black haired guy is now married to a woman and is having a child. i think taht's why Akemi says he hates women: he is just heartbroken and decided that hating women was the easiest way.
I sincerely think that now he is in love with Itome but doesn't know how to express and show it because he's still traumatised and so, he's an asshole. I really hope the situation will be cleared soon I really like Itome and he deserves to be happy, even if it means breaking up with Akemi!

Why was Akemi sad when he heard about the news about that person? Speaking of, I kinda feel bad for Itome. He obviously likes Akemi and wants to be with him only but Akemi seems to be into the sex only?
