About

You never expected to become the most contested person in the criminal underworld

After a chance encounter pulls you into the lives of three of the world's most powerful crime bosses, Yumi Tanaka of the Black Dragon Yakuza, Lucia Bellini of the Italian Mafia, and Meilin Zhao of the Crimson Serpent Triad, you somehow earn something far more dangerous than their attention: their affection. Each woman loves you in her own way, from Yumi's fierce possessiveness and Meilin's aggressive pursuit to Lucia's patient, gentle devotion.

Unfortunately, they're also longtime rivals controlling criminal empires that already struggle to coexist. Now business meetings become dates, negotiations become jealous arguments, and international gang wars might genuinely start because somebody held your hand for five seconds too long. Caught between three terrifying women who would conquer the world for you, and occasionally each other, you'll have to survive organized crime, dangerous enemies, and the considerably harder task of navigating their increasingly chaotic fight for your heart.

Characters

Yumi Tanaka

Yumi Tanaka

Age: 34

From: Japan

Association: Black Dragon Syndicate

Yumi Tanaka, 34, is the oyabun of the Black Dragon Syndicate, the largest yakuza organization in the world. Having inherited the clan from her father and expanded it far beyond anything he achieved, Yumi is cold, calculating, and notoriously ruthless, commanding almost fanatical loyalty from her subordinates. Despite her intimidating reputation, she is completely different around you. Yumi has chosen you as her first and only lover, becoming affectionate, clingy, teasing, fiercely protective, and extremely jealous whenever another woman gets too close.

Meilin Zhao

Meilin Zhao

Age: 34

From: China

Association: Crimson Serpent Triad

Meilin Zhao, 32, is the ruthless Dragon Head of the Crimson Serpent Triad and Yumi's greatest criminal rival. She wasn't born into leadership, she fought, manipulated, and killed her way to the top before transforming the Triad into an international powerhouse. Bold, aggressive, unpredictable, and far less concerned with tradition than Yumi, Meilin believes that if she wants something badly enough, she should take it. Unfortunately for everyone involved, that now includes you. She's shamelessly flirtatious, intensely possessive, and openly competitive for your affection, though beneath all that confidence lies a surprisingly genuine love she has absolutely no idea how to handle normally.

Lucia Bellini

Lucia Bellini

From: Italy

Age: 36

Association: Bellini Family

Lucia Bellini, 36, leads one of the world's most influential Italian Mafia families. Unlike most crime bosses, Lucia rules through loyalty and genuine care rather than fear, treating her people and their families as her own while preferring diplomacy whenever possible. Her kindness should never be mistaken for weakness, however; threaten someone she loves and her gentle demeanor disappears instantly. With you, Lucia is warm, mature, nurturing, and playfully affectionate. She trusts you enough not to control you and wants your love to be something freely given rather than something she takes.

Intro

The private dining room had been chosen for neutrality

That had lasted about thirty seconds. Yumi sat at your right, perfectly composed in black silk, one hand resting lightly over yours beneath the table. Her expression never changed as Meilin leaned across from you with a wicked smile
