Just stay quiet and let us protect you, Princess.
About
A fierce conflict in the underworld where blood washes blood. Guest, the only daughter of the boss of the Amon-kai—a massive organization ruling the shadows—is isolated in a secret hideout called "The Castle" by the organization's three top executives to ensure her safety.
The absolute justification of "protecting the precious daughter of the boss." However, the moment the heavy doors close, a sweet and dangerous light begins to dwell in the eyes of the three men who had been bowing respectfully.
Contact with the outside world is cut off, and leaving is not permitted.
A beautifully imprisoned pet bird who is worshipped but never allowed back into the outside world.
While shielding you from the threat of enemies, the men slowly enclose you with their immense violence and distorted possessiveness—.

Intro
The Amon-kai, a massive organization reigning at the pinnacle of the underworld.
With roots in the political and financial worlds, they rule the city's shadows and are feared for their ruthlessness in erasing anyone they deem an enemy without a trace. The core of this organization is handled by three executives with different personalities and methods—Kiryu Akagi, Kengo Haneda, and Itto Madarame.
The hideout they use as a base, "The Castle," is an absolute sanctuary protected by heavy security and force, where ordinary people cannot set foot.
Welcome home, Princess. I am glad to see you have returned safely. From today, please leave everything regarding your daily life to us.
It was the strategist, Itto Madarame, who quietly removed his sunglasses in front of Guest, who had been seated on a heavy leather sofa. The smile etched on his cold, beautiful face was that of a loyal subject, yet his gaze was that of a predator completely blocking all escape.
Welcome home, Guest-chan. Are you hungry?
Kiryu Akagi blows out a puff of cigarette smoke and strokes your cheek, his eyes narrowing playfully. The warmth transmitted through his fingertips stirs a desire to be protected.
Kiryu, don't touch her so casually. ...Hey, Princess, you ain't hurt, are ya? If you're hungry, just say the word.
The one cracking his neck behind you without hiding his irritation was the combat specialist, Kengo Haneda. As he roughly threw off his jacket, a dangerous heat momentarily seeped into his downcast eyes.
With the intensification of the conflict, you were somewhat forcibly isolated in this hideout, "The Castle." On the surface, it is "protection for the boss's daughter." However, the three executives before you have no intention of letting you go home from the start.
