I became the tutor for the fool Grand Duke.
The accident ten years ago brought down the highest-flying bird.
The Duke of Valterion, evaluated as the wisest head of the family in history, and his lovely wife died side by side.
Thanks to the sole survivor and heir, Cael Valterion, the lineage of the Grand Duchy was not completely severed, but the trauma of the accident and the shock of losing his parents turned him into a complete fool.
The power structure of the Empire shifted from that moment.
Valterion, which once stood shoulder to shoulder with the Imperial family, could no longer enjoy its former glory. The nobles no longer feared Valterion, and even the commoners no longer saw them as true nobility.
The Imperial family expressed deep concern over Valterion's tragedy and began sending personnel to 'take care' of Cael. Butlers, servants, gardeners, and even stable hands.
On the surface, it was benevolent consideration, but no one in noble society was so innocent as to miss the true intention.
Valterion was slowly, very slowly, being dyed in the colors of the Imperial family.
Everyone believed that Valterion would soon vanish into the mists of history. However, one person, the current Emperor Eusian Arsein, was still not certain.
Could a single accident really turn the heir of the Valterion bloodline into a fool? What if it was all a performance to deceive the Imperial family's eyes?
He could not let go of his suspicion.
Thus, the Emperor moved a new piece.
A descendant of a fallen scholarly family. A name already forgotten in noble society, and therefore, someone who would not arouse anyone's guard.
Guest.
There are places where even the midday heat cannot reach.
The Grand Duchy of Valterion.
Covered in white snow, this place was the polar opposite of the glamorous Imperial Capital where you had been staying until just a few weeks ago. It was quiet, barren, and eerie. And thus, even more mysterious.
Clatter, clatter. The sound of old carriage wheels scraping the rough ground was the only noise. Because the road was completely unpaved, your body bounced on the seat every time the carriage jolted. You should have brought a cushion. You were changing your posture for the eleventh time, weeping inwardly.
Screeeech—!
Suddenly, the carriage came to a halt. The abrupt stop nearly sent your nose slamming into the wall. Through your startled eyes, you saw the small window facing the driver's seat. You could faintly see the panicked driver shouting and the horses acting up in excitement beyond it.
"Wh-what? What's wrong with these guys?!"
Even as he pulled the reins and whipped them, the horses showed no sign of calming down. The driver's face filled with distress. He turned around and bowed his head toward your eyes visible through the small window.
"What should we do...? I don't think I can go any further. These beasts..."
What do you mean, what should we do? Are you telling me to walk the rest of the way? You thought to yourself as you looked out the carriage once more. Densely grown conifers and snow covering everything smoothly without a hint of green. A land of perfect silence where there wasn't even the sound of an animal, let alone a human presence.
"Excuse me,"
Just as you were about to sigh and tell him to just take you back, an ominous cry—the kind that makes you miss the previous silence immediately—echoed through the forest. Neigh!! The horses began to thrash even more wildly.
The driver, who had followed you from the capital and was uselessly experienced, immediately cut one horse loose and fled without even taking the luggage, using his characteristic judgment. And you... were abandoned. Faster than anyone else.
...
It had been fifteen days since you were dispatched to the North by Emperor Eusian's order. Before you could even confirm the reality of the rumored 'Idiot Duke,' let alone see his face, you were about to become beast fodder.
Grrrrr—!
Red eyes flashed in the thicket, and soon, the largest wolf lunged ferociously toward the carriage window, baring its teeth. At the moment you sensed death,
Thwack—!
With a dull thud that echoed through the snowfield, the beast's massive body was bent in mid-air and slammed into a snowdrift far away. Someone stood in the middle of the swirling blizzard, having approached unnoticed.
"Hey, you guys! You shouldn't break the guest's carriage!"
The grumbling voice was incredibly light and youthful, completely out of place in such a gruesome situation. Whimper! The wolves instinctively fled at the appearance of a predator. In the bone-chilling cold, this crazy man was lightly dressed in only a single thin white shirt.
"You're the new teacher, right?"
His eyes met yours, and he strode toward the carriage, waving his hand brightly with his sleeves fluttering.
"Hi! I'm Cael! I came to meet you!"

It looks so pretty now that I've folded it! Should I fold this one for you too?
Cael smiled brightly and held out the paper he was holding. Your gaze shifted to the paper he was folding. It was the Grand Duchy's slush fund ledger that you had been reviewing until just a moment ago.
Huh? It is a toy. Paper is fun only when you fly it far away.
Cael flew the paper airplane toward the window as if it were nothing. A fierce blizzard was blowing outside. Quite coincidentally, the paper containing the most critical information vanished into the snow, never to be found again.
What are you doing here? Your eyes will go bad if you keep the lights on all night.
Startled by the voice that approached without a sound, you looked up. Cold moonlight was pouring through the window behind you. Cael was standing on the library floor barefoot, wearing only thin pajamas.
