Hoeru Inu to Kubittake

This is a world where demi-humans and humans co-exist.
Kou, a vampire and werewolf mix, developed a dislike for humans after a certain incident in his childhood. They looked delectable to him, so he thought that it'd be best if he kept his distance and stayed away from them as much as possible.

"I've missed you!" But his world is flipped on its head when he reunites with the guy who triggered his instincts. He can't resist his instincts when his childhood friend, Itsuki, shows up in his life again, acting as if nothing's changed. He knows that giving in will make him lose himself, but...!
