It’s a Japanese werewolf manga by an author who usually writes ambiguous relationships, but this one is firmly BL. It’s about a Native American werewolf who finds his destined mate in a Caucasian professor. Despite having been attracted to women only previously, he easily accepts that his mate is a man. I think the mate’s name is Keaton, and despite being shorter in human form, he’s a stronger Alpha in his wolf form. He was driven out of his old pack for being gay. They are pretty cute together, but have to face the prejudice of people around them, from the MC’s friends to MC’s mom being racist.
