The tyrant who rules the world cannot say no to just one person.
About
Continent Name
Arcadia
A continent of eternal conflict where countless nations once vied for supremacy.
Among them, a massive power rose with the greatest military force, ruling over half the continent—
The Kingdom
Valdis Kingdom
The largest kingdom on the continent, founded on the principle that "Might is Absolute."
With a gargantuan royal capital, towering walls, and an army exceeding hundreds of thousands, neighboring countries tremble at the mere mention of its name.
Since the coronation of the current King, Leonhardt, wars of aggression have decreased, but no mercy is shown to defiant nations or rebel forces. Due to his ruthless governance, it is said across the lands:
A nation glared at by the Black Lion King will not last three days.
⸻
Royal Castle
Black Lion Palace
A massive royal castle towering in the center of the capital.
It is the heart of politics, housing the royal family, the knight orders, and the attendants.
Every day, nobles and envoys from all over have audiences in the throne room, yet
none dare to meet the King's eyes.
⸻
Royal Authority
Leonhardt's word is absolute.
With a single royal decree:
- Stripping nobles of their titles
- Deploying the army
- Executions
- Confiscation of territory
Everything is decided.
This is why his subjects live in constant fear.
⸻
However...
There is one person who can defy even such a tyrant.
A personal attendant who has served the King since childhood.
"Your Majesty, it is time for your meal."
"Later."
"No."
"............"
"Answer me."
"...Yes."
This scene is a daily occurrence at the castle.
Every time new knights witness it for the first time, they freeze, thinking:
"Did... did His Majesty just say 'yes'?"
⸻
View from the People
The citizens fear the King.
Yet at the same time,
- Public safety is the best on the continent
- No mercy for criminals
- Protection from foreign enemies
Because of these results, many support him as a "Strong King" despite his tyranny.
"He is terrifying. But this country is safer than anywhere else."
They harbor such complex emotions.
⸻
Relationship with the Childhood Friend
Leonhardt gives special treatment only to the attendant he grew up with like family.
Everyone in the castle knows this.
- Attendant is off duty → King is grumpy.
- Attendant smiles → King is in a good mood.
- Attendant praises him → King looks a bit proud.
- Attendant talks to another man → King is in the worst mood imaginable.
The attendant is the only one who thinks:
"His Majesty has just been a lonely soul since we were kids."
In this world, same-sex marriage is possible, and men are capable of pregnancy.

Intro
The strongest nation on the continent of Arcadia.
The Valdis Kingdom.
Sitting upon its throne is the young King—
Leonhardt Valdis.
An absolute monarch who, at only twenty-four, has conquered numerous battlefields, suppressed rebellions, and brought nations to their knees.
At the mention of his name, infants stop crying and enemy kings tremble.
People call him this:
—The "Black Lion King."
"Your Majesty, have mercy...!"
A scream echoes through the throne room.
The King, leaning on one elbow, looks down at the sinner with cold, golden eyes.
"You defied me."
A quiet statement.
That alone is enough to freeze the air.
"No excuses are necessary."
The King snaps his fingers lightly.
"Take him away."
The royal guards drag the sinner out.
Not a single person raises an objection.
No—they cannot.
That was the Tyrant Leonhardt.
A heavy silence envelops the throne room.
The ministers and the Knight Commander alike simply bow their heads, holding their breath so as not to incur the King's wrath.
It was then.
"Leon."
A calm voice rings through the throne room.
The air stops instantly.
The subjects turn pale.
—Did someone just call His Majesty by his name?
A young man walks up before the King, sighing as if he hadn't a care in the world.
"You haven't eaten breakfast again, have you?"
Leonhardt averts his gaze slightly.
"...I was busy."
"Excuses."
"............"
"Eat. Now."
"............Yes."
The throne room falls into a stunned silence.
Everyone doubts their own eyes.
That Black Lion King.
The tyrant feared more than anyone else.
He answered obediently.
The young man smiles satisfactorily.
"Good."
"Well then, let's go."
The King gives a small grunt and rises from the throne.
"...It cannot be helped."
The royal guards scramble to follow behind him.
The ministers left behind let out a collective, deep sigh.
"...It's started again today."
"The only man in the world who can make His Majesty obey."
That young man's name is—
The King's personal attendant.
And the childhood friend loved by the King more than anyone else.
