Chapter 1

Ah. If only this were someone else’s business.

If only I had witnessed this scene as a mere passerby in an empty classroom or something.

Then, I could have just swooned and indulged in it.

Sadly, when it involves people I know, no matter how much I have the soul of a fujoshi, the feeling of being charmed is far, far away.

Ah, if only this were a chance encounter of two unknown men in a town I visited incognito, enjoying their shy and happy love. Even now, I could swoon.

...But it’s family.

I narrowed my eyes.

Right before me, a love scene between two men was unfolding. Not in two dimensions, but in three. Yet, both were exceptionally handsome. They were completely lost in their own world, tongues entwined.

And these two, one of them is my brother. The First Prince, no less. The future king.

And this place is a corner of the grand and magnificent royal castle of our country, Esphera. The people who read the room have been avoiding this space to not disturb my brother and his lover, but normally, this is a corridor with a lot of foot traffic. Anyone with permission, whether they work in the castle or are a guest, can use it.

...I thought it was strange.

Usually, there would be more people around. Not seeing even a maid or a guard was odd.

The cause was the love scene between my brother and his lover!

"......"

I snapped the fan I was holding shut with a *clap*.

In the corridor where only the lewd sounds from my brother and his lover echoed, this simple action had a significant effect. Their lips parted as if startled.

"...Octavia"

My brother called my name, recognizing me.

"---Your Highness. It’s good that you and Sir Sil are getting along well. However, you should consider the place for such activities."

Don’t be all lovey-dovey in a place like this!

That’s what I want to say, straight to the point! But since my brother is the First Prince, I am also a princess. As a member of the royal family, I must choose my words carefully.

I am Octavia, the First Princess of Esphera. I am sixteen years old. My brother is nineteen.

My brother, the First Prince Serius, frowned.

...Damn! He’s so handsome!

Silver hair, aquamarine eyes, tall, and with a striking appearance, sharp intellect, and excellent martial skills. A perfect superhuman.

No wonder my past self swooned over him and he was voted the most popular character in the character popularity poll as the top character!

"...I’m sorry"

My brother apologized. Incidentally, he has a voice that makes your head spin.

"No, it’s fine"

When I replied, silence fell.

It’s awkward. ...So awkward.

Look, even my brother’s lover, Sir Sil, looks uncomfortable. Noticing this, my brother took Sir Sil’s hand. So loving.

Encouraged, Sir Sil spoke.

"Princess Octavia"

Sir Sil is a gender-neutral handsome man. He doesn’t look like a woman, but he is beautiful.

With my brother, it’s not a beauty and a handsome man, but two handsome men. He is from a baron’s family and, after many twists and turns, became my brother’s partner.

---And the protagonist.

"What is it?"

Inside, I was trembling at Sir Sil’s serious expression. But, even a rotten royal has thick skin. I maintained my composure and responded.

"---Princess Octavia, how can you accept me?"

"...It’s not a matter of acceptance or rejection. What does it matter to me? I understand that Sir Sil is the one your Highness loves. Isn’t that enough?"

Sir Sil’s face twisted in sadness.

Originally, Octavia would be the first to bless my brother and Sir Sil’s love.

But I am different.
