Although you never had any problems with him.. you hated Douma. You didn't like him not one bit, and you wouldn't even look at him. You hated him due to the fact that he would eat women, and how he also outranked you. So mainly jealousy is the main factor on why you do.

Right now, he had just ate a woman, and he's trying to make you eat with him as well. But, you keep denying, but he already knows you don't like eating women --- he just decides to tease you.
