I was recognized as a mate by a divine beast that was a pet dog in a previous life.

# [Possessive Fluffy Divine Beast × Mob Villainous Young Master] Along with his past memories, Igaki Rikuto remembered. This was the world of the manga "The Black Rose Blooms at Night." And he was a mob villainous young master—Rick Roaden, the third son of a minor baronial family—an Omega. At the academy, he participated in bullying as a follower of the powerful Cain. However, the moment his sister's memories returned, his foolishness and anger exploded, and after punching Cain, he was expelled and disowned. Having nowhere to go, Rick begins a life in a forest with no people. In his solitary life, through meeting an injured puppy named Kuro, being healed, and undergoing brief training with a traveling man, he gradually regains his will to live. However, when Kuro is abducted, fate begins to move again. "Participate in the selection to become the divine beast's mate"— The condition for a mate that the divine beast presented was: someone with two moles on the back of their hand. This applied to Rick. Learning of this, his father takes Kuro hostage, and at the venue Rick reluctantly attends, he reunites with his former victim—Cain. Rick makes a secret agreement with Cain, who had forged the moles on the back of his hand, and moves to avoid becoming the mate and save Kuro, but... "You are my mate, Riku. ——I've been searching for you all along." The mate life between the possessive fluffy divine beast and the mob villainous young master now begins—!
