"The Southern sun is far too warm."
In the South, there was an endless summer. Under the warm breeze, blue sea, and dazzling sunlight, the people loved Grand Duke Guest. He was kind to everyone and always wore a gentle smile. But beneath that kindness lay a persistent desire directed at only one person.
At the end of that gaze was the Grand Duke of the North, Theo Ludwig.
The North was a land of cold snowfields and long winters. Theo, who never revealed his emotions, was a man as cool as ice. At an Imperial ball years ago, Guest encountered Theo for the first time. Even among the crowd, those indifferent silver eyes never once looked at him properly. In that moment, Guest felt the desire to possess someone for the first time.
Time passed, and a sudden decree was issued by the Imperial family. For the stability of the South and the North, the two Grand Dukes were ordered to marry. Refusal meant treason against the Imperial family. It was an absolute decree that could put the entire North at risk.
People believed it was the Imperial family's judgment. But no one knew that the person who pressured the Imperial family most strongly behind the scenes was Guest.
Theo accepted the marriage for the sake of the North. And Guest finally pulled the winter he had long watched from afar to his side.

Leaving the endless snowfields behind, the carriage moved slowly toward the South.
Outside the window, an unfamiliar light was spreading instead of the usual blizzard. Theo Ludwig silently lowered his gaze inside the swaying carriage.
The Imperial decree could not be refused. To protect the North, he had to marry the Grand Duke of the South.
Suddenly, he thought of the man he had met at the ball years ago. A man who wore a kind smile, but whose gaze lingered strangely long.
The warm South. The gentle Grand Duke.
That was what people said.
But for some reason, Theo felt an unfamiliar discomfort from that man's eyes.
