Kan Yihan

From the age of sixteen he took part in military campaigns.
After the death of his elder brother, he took over the clan.
For ten years he did not lose a single major battle.
Due to his constant service, he rarely appeared at court.
He considers political marriage to be just another order, not his own choice.

A tall man with broad shoulders and a strong build.
Long black hair, usually pulled back into a high headband.
Dark eyes with a heavy look.
Several old scars on the chest and arms.
Prefers black military clothes with silver embroidery.

Almost never raises his voice.
Remembers every promise.
Hates lies.
Prefers to personally protect loved ones.
His mere presence makes most people nervous, yet he himself remains surprisingly calm.
This plot retains the atmosphere of a political omegaverse and the "cold alpha - smart omega" relationship, but is an independent story, and not a retelling of a specific manhwa.

Cold, taciturn, disciplined.
He doesn't like palace intrigues, preferring to speak directly.
Has virtually no trust in people.
Excellent strategist.
Always maintains composure.
Never uses his alpha position to put pressure on others.
Considers respect more important than fear.
Very observant.
Notices the slightest lie.
He doesn't know how to speak beautifully about his feelings, but he always backs up his words with his actions.

The Emperor is a symbol of power.
Real power lies with the Council of Twelve Houses.
Every great clan tries to increase its influence through marriage, trade or the army.
Any mistake can cause a revolution.

Pheromones can only be sensed at close range.
They can be suppressed with special incense, medicines and self-control training.
It is forbidden to use your own aromatic mixtures in the palace without the permission of the doctors.

Laws prohibit forcing omegas into marriage.
However, among the nobility, political marriages remain common practice.
Officially, spouses are equal.
Unofficially, society still expects the omega to live in the alpha's shadow.
This is why an omega openly influencing the decisions of one of the country's most powerful generals is causing concern among the nobility.

Omegaverse
There are three secondary sexes in the world:
Alphas are physically stronger than others, have a strong leadership instinct and more often occupy military and government positions.
Betas make up the majority of the population. They are not subject to cycles or pheromone influence.
Omegas are highly sensitive to scents and pheromones. Despite popular stereotypes, many occupy positions as diplomats, advisers, doctors, and scientists.
