Mafia Mayhem #5

The Oyabun's Boy
Mafia Mayhem 5


~ Kenji ~
I saw him dancing in the rain and became intrigued. I wanted to know more, but I never imagined I’d find a man who would become my obsession. I didn’t anticipate the joy he would bring into my dark world or how dangerous I would become to keep it…to keep Joy. Those that threatened him needed to be warned. I’d burn the world down to keep him dancing in the rain.

~ Joy ~
Everyone deserves a little Joy in their lives. At least, that’s what my mama always said and she loved me. Despite the fact that my father was a miserable bastard, my mama and I lived a good life running a cat café together. I lived my life one joy filled rainbow at a time.

When a mafia man became obsessed with me, I should have been afraid. I should have run as far and as fast as I could. Instead, I found myself running into his arms because it was the only place I truly felt safe when the world around me started to burn.

This book felt completely disconnected from the rest of the author’s books. The tone came across as strange and unnecessarily pretentious, which made it hard for me to connect with the story or the characters. Unfortunately, it just was awful, I didn't like it.

Kenji’s life is steeped in darkness until the moment he sees Joy dancing in the rain — a moment that sparks fascination, then obsession. Joy becomes the light Kenji never expected, and he’ll do anything to protect that brightness, even if it means unleashing the dangerous side of his mafia world on anyone who threatens him. Joy, raised by a loving mother and surrounded by the warmth of their cat café, lives life with optimism despite a difficult father. When Kenji, a powerful mafia man, becomes fixated on him, Joy knows he should be afraid. Instead, he finds unexpected safety in Kenji’s arms, especially as chaos begins closing in around him. Their story is one of obsession, protection, and unlikely comfort — a dark man willing to burn the world down for the one person who brings him light, and a gentle soul who discovers that sometimes the safest place is with the most dangerous man.

I loved this story which blended dark obsession with surprising tenderness in a way that’s genuinely compelling. Kenji is a dangerous man whose world is built on violence and power, yet the moment he sees Joy, everything shifts — and the threats closing in on them both feel sharp and real. What really stands out, though, is how the book flips expectations: Joy may be soft, bright, and gentle, but he’s far from fragile. His quiet resilience becomes its own kind of strength, the one thing even a mafia enforcer can’t control or contain. The contrast between Kenji’s ruthless protectiveness and Joy’s steady, luminous courage gives the romance its emotional punch. Their connection feels like two very different kinds of power colliding — one forged in darkness, the other in light — and the danger surrounding them only makes that bond more intense. A gripping, unexpectedly tender romance about the strength hidden in gentle souls and the lengths someone will go to protect the person who brings them hope. This was an MM story with mature content.

This has undertones of Beauty and the Beast, if Beast is mafia boss
