Tsurenai Kemono ni Kamitsukitai

Manager Kyosuke Kozuka from the Fox race is hired as the exclusive manager of a popular model from the White Tiger race, Ojiro Mifuyu. Despite being quite renowned for his skills, Kyosuke worked hard to hide from others around him that he is an Omega to survive in a society with strong prejudice against his animalistic gender. But one day when Mifuyu touches him in the dressing room, an unexpected heat happens...!? "I'm the only one who is allowed to have sex with Kyosuke" says the younger, more passive alpha model.
