My Fiancé Fell in Love with My Older Sister. After Locking Myself in My Room for Five Days, 500 Years Had Passed. - Chapter 1

“…I’m sorry. She is my destiny.”

With a pained expression and voice, he said those words.

He looked as if he were a sinner being condemned.

And as for me—

(…Destiny. In other words, his destined person is…)

My older sister.

I was so shocked—no, completely stunned—that I couldn’t say a word.

Perhaps mistaking my silence for rejection, my fiancé, Lord Felix, bowed his head to me.

“I’m sorry. But this is something that can’t be helped. I’ve met my destiny.”

Felix, my fiancé, was the only son of the royal family and the crown prince.

I couldn’t possibly allow someone like him to bow his head.

Panicking, I quickly spoke.

“Please stop! Raise your head!”

—Destiny.

It is a bond where matching marks appear on the backs of two people’s hands. When that happens, they are recognized as lovers blessed by the gods.

Previous relationships, engagements, even marriages—all of them lose their power before the Destiny System.

That’s how strong and absolute this system is.

But in reality, this Destiny System rarely manifests. In this country, Tsao Beller, it had long been considered nothing more than a superstition.

I never thought I would witness it firsthand.

And the ones involved were my fiancé—

(Wait, so that means…?)

I pressed a hand to my forehead.

Felix and I are engaged…

And my fiancé’s destined partner is… my older sister?

(What kind of messy drama is this?! A soap opera…!? Is this a midday soap opera!?!)

The moment I had that thought, I tilted my head.

(…Huh? What’s a ‘soap opera’ again?)

As I tried to understand why such a thought had come so naturally to me, I heard Felix’s voice again.

It snapped me back to reality.

(Oh, he’s still talking…)

With a desperate expression, Felix was trying to convince me.

“I really tried to love you. But it’s impossible now. Destiny has appeared… and now, I have to prioritize her. My instincts tell me to.”

(Are you an animal??)

(A mindless beast??)

Wait, isn’t this basically brainwashing or something—

I quickly cut off that train of thought.

(What was that just now?! That’s way too disrespectful, Felicia Frenzel!!)

Felix has met his destiny.

Isn’t that wonderful? A beautiful thing.

I should be happy for him.

The crown prince of our country has found his destiny. As a subject of the kingdom, I must celebrate it.

Even if… his fiancée is me, and his destined one is my older sister—

Just as I was forcing myself to think that, he called my name.

“…Felicia?”

“—”

(Feli…cia…)

That was my name.

In that moment, an overwhelming flood of unfamiliar memories rushed into my mind.

A world I’d never seen. Sights I’d never known. A completely different set of common sense from this one—

I gasped.

(Are these… memories from my past life?)

I hadn’t remembered everything.

But even recalling just a part of it was enough to send me into a complete state of confusion.

“Felicia, what’s wrong?”

“I… um…”

My eyes darted around.

I—I am Felicia Frenzel.

The second daughter of the Frenzel Ducal House. Eighteen years old.

Yes, that’s right. No mistake.

My memories aren’t mixed up… or at least, they shouldn’t be.

As I nodded to myself, Felix spoke in a quiet voice.

“So… you really can’t forgive me, after all.”

Startled, I looked up.

And at that moment—

A voice, as soft as a ringing bell, called out from behind me.

“Lord Felix…! Felicia…!!”

A thin, fragile voice—

Even if I stood on my head or did a cartwheel, I could never produce a voice like that. So weak, so delicate.

The owner of that voice was—

“Sis—”

“Agnes!! Why did you come here?! I told you to stay in bed!!”

My voice was cut off—by my own fiancé.
