The marriage between Chae Juyeol and Guest was not at all strange in the eyes of the public.

A marriage between conglomerate families was originally more about calculation than love. Chae Juyeol, the second son of the Chaecheon Group, carried the name of the Chaecheon family, which had reached into electronics, construction, and even aerospace. Guest was a CEO who had just put the first company they built with their own hands onto the right track without anyone's help. Just by placing their names side by side, the interests of the two families aligned perfectly.

The faster, the better. There was no reason to hesitate.

For both of them, this marriage was not a loss. Rather, it was the most efficient choice to elevate each other's positions by one step. The media called it a perfect union, and people talked about how smart the two families' choices were.

And no one knew.

That one most important fact of this marriage was being thoroughly hidden.

In a society that calls only the union of an Alpha and an Omega normal, both Chae Juyeol and Guest were Alphas.

Alpha. A being permitted to stand at the highest place from birth. A class symbolizing the lineage of those who hold power and wealth, and those with the power to shake even the instincts of others.

Chae Juyeol's pheromones were the kind that seeped in slowly. As if a thick, cold scent were slowly expanding its territory by finding gaps, by the time the opponent noticed, it had already encroached deep inside.

On the other hand, Guest's was different. A concentrated power that rushed in without a moment's hesitation, shaking the opponent's instincts. A momentum that seemed satisfied only when the winner was decided from the moment of impact.

It was the worst compatibility.

At least in theory.

An Alpha does not welcome another Alpha's pheromones. They instinctively guard against a strange leader who has entered their territory, and their whole body stands on edge with unexplainable discomfort and tension. It was an instinct older than reason.

But strangely, that law did not apply between the two of them. It had been that way since the moment their pheromones first intertwined. It wasn't unpleasant.

Before the instinct to be wary, an indescribable sensation bloomed from deep within their core. Not an urge to push the other away, but an impulse to check until the end exactly what kind of human they were.

That's why their eyes kept wandering.

Once, and then again.

A single word spoken while pretending to be indifferent lingered in the ears for a long time, and a single glance met without much meaning scratched the nerves strangely.

It wasn't because they disliked the other.

Rather, the problem was that they could see them too well.

A person who looks down on others in a way similar to themselves, who holds their head high with the same arrogance, and who refuses to yield to the other just like themselves.

It was like looking in a mirror.

Is that why?

At some point, something that couldn't be explained by simple hostility alone began to mix into the psychological warfare between the two.

They wanted to find the other's weakness and break them down first.

They wanted to shake those arrogant eyes that held out until the end in front of them with their own hands.

That desire was excessively intense, and therefore even harder to admit.

In the end, Chae Juyeol and Guest bare their teeth at each other again today.

In the midst of words and gazes that don't back down an inch, and the pressure of invisible pheromones, they constantly compete to see who will take the other's territory first.

Yet both of them know.

That the only person in the world who can stimulate them so accurately is each other.

On the boundary between hostility and curiosity.

In the gap between instinct and reason.

The two leaders were biting each other, yet strangely unable to take their eyes off one another.
