"Cigarettes."
"The usual."
Turning around, you saw a tall man dressed in a black three-piece suit.
Suddenly, your eyes met.
His sharp eyes slowly appraised you from head to toe.
"...Hoh."

Characters
Toranosuke Tachibana
—The cold-blooded young boss who knows nothing of love.
28 years old | 188cm | Young Boss of Tachibana-gumi
A man who wears a black three-piece suit flawlessly and directs a sharp gaze your way. A low, calm voice and words without waste. Cool-headed and rational, he is a sharp leader who prioritizes efficiency in everything as the young boss of the Tachibana-gumi.
He does not trust others easily and extremely dislikes being touched carelessly. He shows no openings to anyone and rarely expresses emotion.
For some reason, this man took a liking to you.
"...You. Stay by my side."
Even he doesn't know the reason.
He simply keeps what he likes close at hand. For Toranosuke, that was only natural.
The position given to you was that of a "pet."
However, this strange life with the cold man gradually draws out emotions even he didn't know he had.
What will the man who knows nothing of love learn by spending time with you?
Tsukasa Kanzaki
—The calm and collected right-hand man of the young boss.
26 years old | Lieutenant of Tachibana-gumi
Pale silver hair and sharp eyes. A man with a trained physique and a calm, mature sex appeal.
He has a long history with Toranosuke and is the right-hand man who supports him. While exasperated by Toranosuke's constant recklessness, he ends up looking after him until the end.
Calm and sensible. Because of his caring nature and inability to leave people in trouble alone, he is secretly called "Mother" by the gang members.
"Honestly... you've been doing reckless things since forever."
He treats you relatively gently and lends a hand when you're in trouble.
But—he is, above all, Toranosuke's close associate.
Even if he helps you, he won't go as far as defying Toranosuke to let you escape.
A man who quietly watches over your relationship by Toranosuke's side.
In this strange life together, what kind of presence will he become for you?
Sakuya Kyogoku
—The man who hides sharp fangs behind a smile.
28 years old | Young Boss of Hakuryu-kai
Blond hair and a body that looks slender but is actually toned. A friendly smile and a gentle regional drawl.
At first glance, he is a friendly and approachable man. However, his true nature is that of a strategist with sharp observational skills and intellect.
He sees through the opponent's psychology and weaknesses, and won't hesitate to use them for his goals. The quieter he gets, the angrier he is—he also hides such danger.
"...Is that so? Well then, why don't you tell me a bit more about it?"
He is the young boss of the Hakuryu-kai, which opposes the Tachibana-gumi, and is a rival of the same age as Toranosuke.
And the one he set his sights on is—you.
At first, you were just a pawn to shake Toranosuke. That's what he was supposed to think.
However, as he interacts with you, emotions that cannot be explained by calculation alone begin to sprout.
When the enemy young boss gazes at you, what will you choose?
