My Fiancé Fell in Love with My Older Sister. After Locking Myself in My Room for Five Days, 500 Years Had Passed. - Chapter 26

“……Th-this.”

“It is a unique magic of enchantment.”

Prince Lian said it clearly and without doubt. Then, he fixed his cufflinks and smoothed down his sleeves.

“Would you mind listening to a bit of my old story?”

☆

Lian Lumos had a childhood friend. But Lian was a member of the royal family.

Once the Empress started taking him to tea parties, he began meeting many noble sons and daughters. She was one of them.

Lian had many people he could call childhood friends. If it’s just about knowing them since childhood, then yes, they were childhood friends.

But that didn’t mean they were friends.

She had feelings for Lian. It was probably a young girl’s deep admiration—like love.

She tried to get close to Lian many times, but even back then, Lian was only interested in magic and didn’t like being around her.

She had no hesitation, like someone barging into your heart with shoes still on.

To put it nicely, she was sociable. To put it harshly, she was pushy and too familiar.

She was probably just desperate to get close to him.

But Lian had a dream. That was—to break the seal on the Sealed Room door.

For five hundred years, no one had been able to open that cursed door. Inside was said to be a witch, betrayed by her fiancé, asleep in sorrow and despair.

Was she still sleeping in that room now?

What did the witch look like?

If Lian managed to break the seal and open the door…

Could he wake her up?

Once he started thinking about it, he couldn’t stop. Lian imagined many different possibilities.

He was too busy for socializing. But she kept visiting him, ignoring that.

Even spending time with her felt like a waste, and Lian avoided her more and more.

Unlike his serious and dependable older brother, Lian was always curious and had a scholar’s mindset.

If something caught his attention, he had to research it. That curiosity was so strong, he could read and understand ancient documents even as a child.

For five hundred years, no famous scholar or powerful magician had ever broken the seal on the Sealed Room. To solve such a mystery himself—how romantic that would be.

Since he was little, Lian had been obsessed with the secret of the Sealed Room.

When he was fifteen, she finally lost her patience and begged her father for an engagement.

Her father then tried to propose that his daughter marry the second prince to the Emperor.
But her family was an old but powerless lower noble house.

They were rejected instantly. Her father tried to comfort his heartbroken daughter.

“It was just the wrong person.”

If he wasn’t royalty, if he were a commoner, this wouldn’t have happened.

Next time, find someone you can definitely win over, he told her.

But she couldn’t accept it.

Her fate was with him.

This was destiny, the will of the gods… She was sure of it.

“…Is everything clear so far?”

Prince Lian paused there
.
His voice was calm, without emotion.

I tried to sort out my thoughts and answered while still confused.

“…But earlier, you said there are no people in the Lumos family who can use unique magic anymore.”

I repeated what he said earlier. Prince Lian furrowed his brows slightly. He lowered his lashes, then continued with a tired tone.

“…There’s more to the story.”

He went on, slowly.

“Her family, before they lost their title after losing in the First Great Magic War, was a well-known noble house throughout the country.”

He had said the First GreT Magic War started when Count Aaron Spender rose up against the Tsobellar kingdom.

So if her family lost in that war and lost their title… That means her family was once a noble house in Tsobellar.

When I realized that, my eyes widened.

Prince Lian looked straight at me and said:

“You probably know it too. Her family— Five hundred years ago, during the Tsobellar dynasty—
held the title of duke under the name Abercrombie.”

Abercrombie… Duke…

Suddenly, one man’s face came to mind.

It was—

(Arnold Abercrombie…!!)

That man’s name.
