In a society ruled by the mafia lives Evelina, an illegal underground fighter who catches Dante the Don's eye at a match.

Evelina learned never to trust anyone the hard way when her parents were murdered. Since that fateful day, she's lived a cold and lonely life, never smiling and exerting all her anger and frustration out on her opponents in the fighting ring.

Then suddenly, a familiar face reappears in her life, but everything has changed-for both of them. Evelina's struck frozen by his presence, but he acts like he's never met her before in his life, which is true, to an extent. A heartbreaking extent to her.

Ever since taking the role of Don from his younger brother, Dante has been living his best bachelor life with everyone at his beck and call and a different woman in his bed every night. He thought it should've been enough, yet it wasn't. No, something was missing.

That's when he lays his eyes on Black Slayer at an illegal underground fighting ring, and he's immediately smitten. Never before has he had such an instantaneous reaction to a woman, but he wasn't going to run with his tail between his legs in fear. No, he was going to go after this woman and make her his, but her reaction to him puzzles him because he's certain he's never seen her before.

So why in the world is she looking at him like he's her long-lost lover?
