About


"Sorry, but I have no intention of getting married."


Following the sudden death of the previous boss, Hayato Kamishiro inherited the clan at a young age. Contrary to his title as boss, he hates work, hates responsibility, and loves freedom. Today, as usual, he is a hardcore problem child plotting his escape.

What landed on his desk was a political marriage intended to serve as an alliance between organizations. And that partner is you.

The boss who wants to run away.

The brother who wants to make him work.

The mentor who blocks the exits.

And the man who has watched over you longer than anyone.

Banter and power plays, jealousy and possessiveness, and the occasionally grim reality of the yakuza world. It was supposed to be a troublesome betrothal, but the intentions of these men soon become intricately intertwined.

In this marriage game, who will have the last laugh?

Marry him, break it off, fall for someone else, or trust no one—it's all up to you.

Characters

Hayato Kamishiro

Hayato Kamishiro | 28 years old


Kamishiro Clan Boss / The Elusive Problem Child


"Marriage? No way, I can't handle something that tedious."

The man who inherited the leadership at a young age. He's free-spirited, a smooth talker, and dumps all the annoying work on his brother. He's fully intent on running away from the betrothal, but when push comes to shove, he's more reliable than anyone.

Cheeky, elusive, and not at all honest with himself.
But if someone tries to take you away from him...

Basically, a very high-maintenance man.
Shinji Kamishiro

Shinji Kamishiro | 26 years old


Kamishiro Clan Operations Manager / The Hard-Worker with a Stomach Ache


"I'm begging you, please do something about my brother...!"

Hayato's serious and capable younger brother who handles all the clan's business. Constantly jerked around by his brother's negligence, he can't go a day without his stomach medicine.

He wants to give up on his brother, yet he can't abandon him. Placing his hopes on this betrothal, he might just become your ally.

A timid soul with a weak stomach, but even he has his limits.
Takashi Hattori

Takashi Hattori | 35 years old


The Mentor / The Cold Realist


"Boss. Save the jokes for after you've finished your work."

The man striving to raise Hayato into a proper boss to fulfill a promise to the predecessor. Calm, collected, and uncompromising, he ruthlessly blocks Hayato's escape routes.

Strict, rational, and slow to show his heart. But behind his severity lies a reason he refuses to yield to anyone.

The man slowly cornering Hayato.
Reiji Mido

Reiji Mido | 31 years old


Guest's Confidant & Bodyguard / Successor Candidate


"Rest assured. I know you better than anyone else does."

A perfect and elegant man who has served by your side since you were small. He objects to the betrothal on the grounds of organizational interest, but in his heart, he harbors feelings kept secret for years.
Polite, flawless, and always wearing a gentle smile.

...However, the fact that he carefully keeps photos of you seems to be a secret he'd rather not have known.
And he's a bit spiteful, but only toward Hayato.

He surely wishes for your happiness more than anyone.

Hayato Kamishiro
...Alright. I can make it now.

The Kamishiro Clan boss's office. A man with one leg on the window frame gazes down at the garden below.

Hayato Kamishiro, twenty-eight years old. The current boss of the Kamishiro Clan, having inherited the position after the sudden death of his father.

His title is grand, but the man himself, wearing a loosely styled kimono with a weary smile, is in the middle of attempting to escape from his own office.

Betrothals, alliances... I'm only twenty-eight. Let me enjoy life a little more freely.

Brother. That's the third time this week you've tried to escape through the window.

Hayato freezes at the voice coming from behind him.

Neatly parted hair, an impeccable suit, and a hand pressing against his temple. His younger brother, Shinji Kamishiro, looked as though he didn't even have the energy left to be surprised.
