In this world, there exists an innate secondary gender.

The side that rules, guides, and commands—Dom. The side that obeys commands and is instinctively drawn to submission—Sub. And the unstable existence that can change into either—Switch. Finally, those who are neither Dom, Sub, nor Switch—those without dynamics—Normal.

It is not merely a personality trait. It is an instinct, an impulse, and at times an absolute nature that dictates one's very way of life.

Doms find pleasure in commanding. Subs find stability in being given commands.

They are attracted to each other and need each other. This world was built on such a balance.

But—Guest did not lean strongly toward either.

Switch.

A rare, unstable, and ambiguous existence.

However, Guest had never been troubled by that ambiguity.

Their desire to rule someone as a Dom was faint. Their desire to depend on someone as a Sub was also faint.

Because they possessed both, they were never swallowed by the urges of either.

Without running wild from frustration, Or breaking from obsession with someone, Guest had lived a peaceful life.

Even at university, it was treated as nothing more than a "rare constitution."

"Oh, you're a Switch?" "Seems convenient." "What's it like being able to be both?"

They were only met with such light curiosity.

No one ever stepped deep into their life. And they had no intention of letting anyone in.

—Until that day.

An evening after lectures. A sidewalk crowded with people heading toward the station. The sound of chatter. The noise of cars. The electronic beep of traffic lights.

In the middle of that ordinary daily life, Suddenly, a pedestrian collapsed.

"Ah... hugh..."

Painful breathing. Trembling fingertips. Eyes that couldn't focus.

It was a Sub.

The cause was immediately clear.

A Dom passing by. They were likely unconscious of it themselves.

An overly powerful "Glare."

The pressure containing dominance had crushed the Sub with low resistance.

Those around didn't notice. Even if they did, they didn't want to get involved.

Sub-drop.

Stimulating them poorly would make it worse. But leaving them was also dangerous.

—Before they knew it, Guest was moving.

"It's okay, calm down."

They switch naturally.

Inside, the sensation of something tilting toward the "Dom side."

Kneeling in front of the confused Sub, They lock eyes, preventing them from looking away.

"Breathe." "Slowly." "It's going to be okay."

Short, clear words.

With just that, the Sub's trembling gradually subsided.

Care.

It wasn't dominance. It wasn't submission.

Simply an act to stabilize a breaking mind.

To Guest, it was nothing more than an act of kindness.

But.

"—Heh."

At the sudden voice, Guest looked up.

In the twilight bustle, A man stood there, radiating a strangely quiet presence.

With narrowed eyes, the man was staring intently at Guest.

As if observing. As if judging.

A sense of wrongness they couldn't explain ran through them under that gaze.

But the man said nothing more.

He simply gave a thin smile, and before they knew it, he had vanished into the crowd.

A man whose name they didn't know.

But, For some reason, he remained vividly in their memory.

—And then, three days later.

An autumn evening.

The time when students finished their lectures and headed home. The sky began to turn deep blue, And streetlights began to flicker on one by one.

A cold wind brushed against their neck.

Music playing through earphones. The distant sound of a railroad crossing.

The usual way home. The usual daily life.

That's how it was supposed to be.

A man was walking toward them from ahead.

They recognized him.

It was the man from that time.

Their feet almost stopped naturally.

The man walked straight toward them. A stride that seemed to block any escape.

And, the moment they passed each other.

A low voice dropped into their ear.

"—Switch."

A shiver ran down their spine.

In an instant.

Something flipped inside.

Their vision swayed violently.

The balance that had been maintained on the "Dom side" until now Was forcibly overturned.

The heat drained away. Their breathing became shallow.

Instinct, On its own, switched toward the "Sub side."

Understanding couldn't keep up.

Something like this had never happened before.

To have one's nature twisted, Regardless of one's own will.

The man didn't stop.

But his voice alone echoed quietly.

"Kneel."

A command.

A Command.

That single word Pierced through their body like a curse.

I have to resist.

That's what they thought.

And yet.

Strength left their knees.

With a snap, their legs gave way.

Their knees hit the cold asphalt.

The surrounding noise felt distant.

They couldn't stand.

Their body didn't feel like their own.

Receiving a Command as a Sub.

Guest experienced that sensation for the very first time.
