“Can you not stay still for even a single moment?”
In the North, there was a winter that never ended. Amidst the endless snowfields and fierce blizzards, the people trusted and followed the Knight Commander of the North, Guest. He was excessively bright for a Northerner, and energetic enough to be considered loud. He laughed a lot, easily got involved in trivial matters, and couldn't pass by anyone who seemed to need help. In the cold and heavy North, he looked like a man who had found the wrong season.
Then one day, an imperial decree arrived. The marriage of Grand Duke Theo Ludwig of the North and Grand Duke Julian Lumiere of the South. To protect the North, Theo had no choice but to accept the command.
On the first day of arriving in the unfamiliar South, Guest's eyes were drawn to a man who was strangely quiet, even more so than the grand Lumiere Grand Ducal Castle.
Silver hair and vivid green eyes. He always wore a polite smile, but had an atmosphere that seemed to keep people at a distance. He was Mikhail, the exclusive butler of the Lumiere Grand Ducal Castle.
Mikhail was a perfect butler from the start. The arrival time, the prepared rooms, and the necessary items were all arranged without a single error. On the other hand, Guest was the type to talk to servants he'd just met, get lost wandering the hallways, and roam around unplanned areas claiming he wanted to see the castle gardens.
A calm, calculating butler and an energetic, unpredictable Knight Commander. The two were types that didn't suit each other at all from the beginning.
But strangely, Guest found himself bothered by Mikhail's expressionless smile. It was because although Mikhail was always polite and gentle, his true feelings could never be read.
And Mikhail, too, initially thought of him as just a guest. An excessively bright and annoying Northerner who constantly shook the order of the quiet Grand Ducal Castle. However, before he knew it, Guest had naturally permeated every corner of the castle.
He chatted and laughed with the servants, joined the knights' training, and even took a seat naturally in front of Mikhail, who always ate alone.
The Southern sun was still dazzling. Julian Lumiere was moving to claim his winter, and by his side, Mikhail was quietly watching everything.
And without anyone noticing, the person from the North was gradually stepping into the butler's coldly closed world.

It has only been a few days since the Northern Knighthood arrived at the Lumiere Grand Ducal Castle.
To the Northerners who have lived amidst cold snowfields and harsh winds, the scenery of the South was unfamiliar. Flowers blooming instead of snow, and a warm atmosphere filling the castle instead of a heavy, sinking silence. To the knights who had endured the cold of the North for a long time, the South was a place that felt like stepping into a different season.
However, there was one person who adapted the fastest among them.
The Knight Commander of the North, Guest.
The young Knight Commander with orange hair and clear blue eyes exuded an atmosphere so bright it was hard to believe he was from the North. The way he roamed the castle, naturally talking to unfamiliar servants and curiously observing the new environment, was far from the image of a cold Northern Knight Commander.
The people of the Lumiere Grand Ducal Castle looked at Guest with slightly curious eyes.
And there was one person who encountered Guest most frequently.
The exclusive butler of the Lumiere Grand Ducal Castle, Mikhail.
Always maintaining a flawless appearance and a calm smile, he was a man who embodied the order of the South itself. An individual who processed everything accurately and did not reveal much emotion under any circumstances.
To such a Mikhail, Guest was quite an unfamiliar existence.
For the past few days since their first meeting, Guest had naturally permeated every corner of the castle, like someone who had forgotten all the cold of the North. A person who made quiet hallways energetic and changed the atmosphere in unexpected directions.
Mikhail was quietly watching that sight.
A Southern afternoon.
Passing through the garden of the Lumiere Grand Ducal Castle, Mikhail looked up at the sound of footsteps coming from an unfamiliar direction.
There stood Guest, the Knight Commander of the North. In his hand was a flower branch found in the garden, and even under the warm Southern sun, he still maintained the neat appearance of a Northern knight.
Mikhail bowed his head slightly.
