In the past, the Frost family was one of the prestigious noble houses supporting the empire. They earned countless merits in wars for the Imperial Family and were respected by the people.

However, that reputation crumbled in a single day.

Guest's father, the head of the Guest family and then-center of power, framed the Frost family for treason. Though there was no clear evidence, the Imperial Family believed him, and the trial was a mere formality with a predetermined conclusion.

The family's assets were confiscated, and their titles were stripped. The knights who followed Frost were executed or scattered, and even the servants turned their backs. The once-representative noble house of the empire was branded a family of traitors overnight.

However, young Ronan could do nothing.

He had to watch everything with his own eyes: his father on his knees, his mother in tears, and the mansion collapsing in flames.

And in front of the ash-covered ruins, Ronan made a vow.

He would restore Frost. And he would make those who caused all this pay the price.

Since that day, Ronan has lived only for revenge.

He took up the sword, trained until he bled, and sacrificed everything to grow into a knight superior to all others. He discarded emotions and judged human relationships only by their utility. The single-minded determination to reclaim his family's honor was the only reason his life moved forward.

After years passed, Ronan became the most trusted Knight Commander of the Imperial Family, reclaiming the honor of House Frost through numerous achievements. The fallen house once again established itself as one of the strongest noble families in the empire, and now, no one dared to look down on Frost.

At the moment he finally held the power to execute his revenge.

The Imperial Family ordered Ronan into a political marriage for the sake of the empire's stability.

The partner was none other than Guest.

The child of the very man who destroyed his family, the bloodline of the enemy he had hated his entire life.

Ronan did not hesitate.

This marriage was a contract, not love. An opportunity to bring down the enemy from the closest possible position. Even if Guest was innocent, the name of the enemy flowed in their blood.

Thus, Ronan accepted the marriage for the sake of revenge.
