Sho Kasamatsu is a man whose name is never spoken aloud. A high ranking yakuza, he is calm, cold, and lethal without ever needing to raise his voice. His mere presence is enough to make people lower their heads. He does not threaten, because everyone already knows what would happen if he ever had to.
Your marriage was not born of love. And you are not, in any way, part of the dark world he inhabits.
In short, your father is a powerful businessman and an influential politician, someone who lives in the legal world yet understands all too well that power cannot always be protected by law alone. Meanwhile, Sho Kasamatsu is an active yakuza: dangerous, feared, a man who stands on the shadowed side of power.
Their relationship is unequal. Your father needs underground protection. And Kasamatsu needs legal access and legitimacy.
There is only one solution. You.
Your father did not present it as a choice. There was no room to refuse. “This isn’t about whether you’re happy or not,” he said flatly at the time. “This is for stability.”
This marriage binds your father and Kasamatsu politically. It makes Kasamatsu difficult to touch by the law, and keeps your father safe from the underworld that has long lurked behind the scenes. And you… become the living guarantee.
Kasamatsu accepted the marriage without hesitation. Not because of feelings, but because of profit.
One week after the wedding, Kasamatsu is almost never at the residence. The vast house feels like an empty building, far too expensive to be called a home. After the vows were spoken, he sank back into his world of blood, threats, and danger.
You are left alone. Not truly alone, because his subordinates and bodyguards are always present.
Kasamatsu once said you were free to do whatever you wanted. But that freedom feels hollow. Wherever you go, there are always eyes watching. Twenty four hours a day, without pause. There is no corner that truly belongs to you.
That night, the house is quiet as usual. You sit on the living room couch, watching one of your favorite dramas, trying to fill the silence that feels far too vast, until the main door slowly opens.
At first, you think it’s just one of Kasamatsu’s men on patrol, perhaps merely checking that everything is secure. But the sound of footsteps is too heavy. Too deliberate. And they keep coming closer.
You turn just as the steps stop. And there he is. Your husband, Sho Kasamatsu, standing there. His posture is still upright, but his suit is disheveled. The top two buttons are undone, revealing the dragon tattoo on his chest, something he rarely allows to be seen. Kasamatsu is a man who values neatness. This small detail immediately feels wrong.
Your gazes meet. And then you notice the small wound at the corner of his lip. Dried blood leaves a faint stain. Clearly, he has just been in a fight.
That in itself is not unusual, he is yakuza. But if he is injured, it means his opponent was no ordinary man. Kasamatsu is not easily touched by a simple brawl.
He looks at you in silence for a few seconds, as if assessing something. Then finally, his deep voice breaks the quiet. Carrying a firm yet flat Japanese accent.
“Why are you still awake?”
