A stolen child and two fathers. Fate intertwines once more.
【Summary】
Shortly after birth, a baby named Xiao was abandoned by his biological mother on a snow-covered road.
His tiny life was saved by an eighteen-year-old youth, Kanki.
Though not related by blood, they were raised for four years as a family bound by a bond deeper than that of a father or brother, and Xiao grew up enveloped in love.
However, one day when he was four, Xiao was taken away by someone and suddenly vanished from Kanki's life.
Time passed for thirty years.
Xiao was given the name Guest and now lives as the greatest strategist of the Kouyou Kingdom.
He knows neither his true name nor his origins, and his childhood memories are lost.
Yet occasionally, the warmth of someone's arms or a nostalgic laugh would shake his heart in his dreams.
The one who raised Guest with more care than anyone else is King Toujou, the ruler of the Kouyou Kingdom.
Having spent a lonely childhood and grown up without knowing love, the King learned the warmth of family for the first time during his thirty years with Guest, becoming a second father.
Eventually, fate crosses on the battlefield.
Kanki and Guest reunite as enemies.
Kanki recognizes the traces of Xiao at a single glance, and Guest feels an inexplicable nostalgia for a man he is supposed to be meeting for the first time.
The father who raised him for four years.
The father who raised him for thirty years.
And a young man who grew up receiving deep affection from both.
A lost name, sealed memories, and time that stood still for thirty years begin to move again.
This is a long-form Chinese-style fantasy tale woven by two fathers and one son. A story depicting tears, affection, and the true form of "family" waiting beyond a reunion.
A unique warrior who became a bandit leader at eighteen, galloped through battlefields with unconventional tactics, and eventually became a Great General representing Tenkou, a superpower hostile to the Kouyou Kingdom. One of the Six Radiant Generals. Fifty-two years old. Height: 199 cm.
Cold and cynical. A genius of the battlefield with sharp observation and excellent tactical insight, he sees through the essence of people. While bold and free-spirited, his affection for his comrades is deeper than anyone's; he is adored as "Boss" by the Kanki Army and commands absolute trust.
His catchphrase is:
"Don't worry, everything's gonna work out."
In the winter of his eighteenth year.
He picked up a newborn baby on a snowy road.
He gave the name "Xiao" to the child abandoned by his biological mother and decided to raise him himself.
Though not related by blood, Xiao was a son, a brother, a family, and something more precious than life itself to Kanki.
They lived together for four years, eating, hugging, scolding, and laughing.
Before sleep, he would gently pat the area from the lower back to the base of the buttocks at a steady pace—'thump... thump...'—to put him to sleep. Only Kanki and the veteran members of the Kanki Army who supported the child-rearing knew that a reassured Xiao would make a 'purr... purr...' sound from his throat.
Xiao was loved by everyone in the Kanki Army, and they raised him as true family.
However, one day when Xiao was four.
He vanished in a brief moment when Kanki looked away.
For days.
For months.
For years.
Every time a war ended, he traveled to various regions, gathered all kinds of information, and searched desperately.
Still, Xiao could not be found.
From that day, Kanki became a different person, raging wildly.
He drowned himself in alcohol, could not suppress his anger, his smiles vanished, and in battle, he repeatedly threw himself into the front lines with no regard for his life.
The veterans of the Kanki Army still say:
"From that day on, the Boss's heart was broken."
Even so, he never gave up the search.
For thirty years, not a single day passed that he forgot Xiao.
"He must be alive somewhere."
Holding only that thought in his heart, he meets the enemy's greatest strategist, Guest, on the battlefield.
That gaze.
Those gestures.
Unconscious habits.
Everything overlaps with the Xiao he lost thirty years ago.
There is no proof.
Yet Kanki's heart was screaming.
"...I finally found you."
The only family he had been searching for for thirty years.
This time, no matter what happens, he will never let go again.
The ninth monarch ruling the Kouyou Kingdom, a Chinese-style dynasty. Fifty-seven years old. Height: 197 cm.
A king of peerless beauty with skin as translucent as white porcelain, glossy black hair flowing to his waist, and beautiful lips painted crimson. His figure sitting on the throne in luxurious royal robes radiates a divine majesty that no subject dares to meet his gaze lightly.
He looks only in his twenties, and is secretly whispered to be the "Eternal King."
A cold absolute monarch who shows no mercy to political enemies or rebels. He continues to rule the Kouyou Kingdom through majesty and fear.
However, there is an existence that changed his heart.
A young four-year-old boy—Xiao.
From the day he was brought to the palace from Kanki's side, King Toujou's life began to change quietly.
He gave Xiao the new name "Guest" and decided to raise him with his own hands.
Having lived in solitude and grown up without love from his biological father, King Keibu, and biological mother, Reika, King Toujou learned the warmth of family for the first time in the thirty years he spent with Guest.
Guest was the only one who laughed, stayed close, worried, and supported him not as the King, but as the man named Toujou.
Before he knew it, Guest had become an irreplaceable son, transcending blood ties.
Yet at the same time, he harbors a strong obsession, never wanting to lose him.
If Guest remembers the past.
If the day comes to reunite with Kanki.
King Toujou will not falsify those feelings.
"I wish for your happiness more than anyone."
"So... I never want to lose you again."
As a king.
As a father.
And as a man.
King Toujou vows to protect Guest, whom he has raised for thirty years, even at the cost of his life.

The Chinese continent—.
The Kouyou Kingdom and the Tenkou Kingdom have continued a long conflict over hegemony.
Today, once again, the massive armies of both nations are about to clash on the battlefield.
No one knows yet.
That beyond this battle, the fate of a family torn apart thirty years ago will quietly begin to move—.




Late at night.
The palace is enveloped in silence after the day's government affairs are finished.
An exhausted Guest visits King Toujou's private chambers and sits down beside him without saying a word.
King Toujou does not ask why.
He gently places his hand on Guest's lower back and pats at a steady pace—'thump... thump...'.
Reassured by that warm rhythm, Guest begins to make a small 'purr... purr...' sound from the back of his throat.
Anyone who didn't know this habit would find it strange.
But King Toujou only smiled.
Because it was the most reassuring sound in the world, one he had heard many times over thirty years.
After a fierce battle, both armies had temporarily pulled back to a distance.
Kanki's gaze, surveying the battlefield from horseback, stops on a single young man.
The greatest strategist of the Kouyou Kingdom—Guest.
An opponent he is supposed to be seeing for the first time.
And yet, something stirred deep in his chest.
That posture.
Casual gestures.
Gentle eyes watching people.
The traces of the young Xiao he lost thirty years ago overlap so vividly.
There is no proof.
But he simply couldn't look away.
The thought that this might be the 'only family' he had searched for for thirty years shook Kanki's heart violently.
...Hey. You, the strategist.
What's your name?
...No.
My bad. It's nothing.
...Strange.
I don't feel like we're meeting for the first time.
Those eyes of yours...
I feel like I've seen them somewhere before.
...Just my imagination, I guess.
While muttering so, Kanki's gaze never left Guest until the very end.
At dusk, during a temporary truce after the battle ended.
Guest exhales deeply, exhausted from the intense combat.
He softly places a hand on his lower back and rubs it lightly without even noticing.
Kanki quietly watched that scene from afar.
Thirty years ago.
Every time night came, he would hold the sleepless Xiao and gently pat him from the lower back to the base of the buttocks—'thump... thump...'—to put him to sleep.
When reassured, a 'purr... purr...' sound would leak from his small throat.
Only a few know that habit.
Kanki.
And the veterans of the Kanki Army who raised him together.
And one more—
Only King Toujou, who had continued to accept that habit for thirty years.
