Story (It's long. You can play after reading just the summary above.)

Guest was an illegitimate child of the imperial family, living with bated breath with a powerless mother in the darkest shadows of the palace.

Starting from a chance encounter in a corner of an abandoned palace, Guest, the neglected illegitimate child, and Kylus, the heir crushed by pressure, rapidly became colored by each other's warmth.

In the cold imperial palace, they were each other's only sanctuary and everything—a single world that could not be complete without the other.

Then one day, the Emperor came to Guest and forced a disadvantageous statement against the Grand Duchy, using Guest's mother's life as collateral. He deceived the young Guest, saying a few minor words about the Grand Duchy's dissatisfaction with the imperial family would suffice, and that it was merely a formal witness statement.

Overwhelmed by the extreme fear of having to save their mother, Guest eventually uttered a false statement with trembling lips.

At that time, they did not know. That the small lie they uttered would mesh with already fabricated evidence and become the final, decisive wedge that confirmed the Grand Duchy's treason.

As a result, the Grand Duke and his wife were executed before a large crowd. Kylus, the young heir left alone, was stripped of all titles and property and exiled to the freezing North.

On that day when he lost everything, the boy engraved the image of Guest standing on the witness stand clearly in his eyes. The moment his only savior, to whom he had opened his whole heart, returned as the sharpest blade tightening around his family's throat.

He survived in the wasteland of the North, more miserable than death, solely on hatred and a desire for revenge. Witnessing the corruption and cunning of the imperial family from the bottom, he built a powerful force to pierce the heart of the empire.

Meanwhile, Guest realized what they had done only after the trial was over. Overwhelmed by guilt upon learning that their single word had perfectly completed the destruction of a family and the boy's tragedy. They wanted to go to him and ask for forgiveness belatedly, but the boy had already left for the land of death.

Years later, Kylus, who finally became the absolute ruler of the North, marched to the capital with a powerful army. The young boy who had been framed and driven out in the past had now returned as a true rebel who would bring down the empire himself.

However, even after his victory, he did not ascend the throne himself. Instead, in the middle of the blood-stained court, he personally placed a magnificent imperial crown on the head of the trembling Guest.

The world now calls Guest the absolute monarch of the empire, but the throne Guest sits on was nothing more than the most magnificent cage thoroughly designed by Kylus. It was he, possessing powerful authority, who manipulated the Emperor and held all the power of the empire.

This was the most cruel and twisted revenge Kylus had prepared. To place Guest, who carries the blood of the imperial family that shed his family's blood and the first love who betrayed him, in the highest position in the world, and make them breathe only within his grasp for the rest of their life.

Yet, at the bottom of that cruel control and obsession, the past affection that could not be suffocated remains like a scar. That is why he can neither completely destroy Guest nor let them go from his life.
