From time to time, the empress boasted of the gifts she had received from the emperor and stirred the empress's heart.

She wasn't the only one. She embarrasses the empress with all sorts of tricks and tortures her prince.

Moreover, her empress's family worked tirelessly to injure her mother's family.

'It has led to the loss of her empress's authority several times....'

The emperor wanted everything at this time, and he blamed and resented the empress, and her empress's heart burned more and more.

'It could be that the accumulating core of her heart eventually created an incurable disease. This time, I will definitely cure the disease.'

「Then, legendary relics are also relics, but if you protect her empress from her empress, wouldn't it be possible to prevent her from getting sick in the first place?」

'But we still don't know the exact cause of the disease. It can be really stressful... Maybe she was what the Empress had planned.'

「Then let's put the legendary relics on hold for the worst-case scenario."」

'Great.'

Raphine laughed inwardly.

Just looking at it, Ruby was a huge help.

Raphine reassured her that she didn't have to worry about everything for her alone.

「Hey, you know that now! Anyway, does that mean that a guy named Zerkan doesn't have a good relationship with her only younger brother, her 2nd Prince?」

'That's right.'

「Then it will be very easy to get to know you. Because she doesn't have any other sisters to Zerkan.」

At Ruby's words, Raphine tilted her head.

'What do you mean?'

「Just as Adrian is going to be her younger brother, Zerkan should do the same!」

With those words, Raphine remembered Adrian, who was delighted when he heard the sound of "brother" for the first time.

Obviously, Adrian had only a younger brother, and then suddenly he had a younger sister, and he looked delighted and amazed.

It was the same with her twin brothers, Luca and Lois.

'Then Zerkan...?'

「ight! I'm sure you'll be able to entice me very easily!」

'Hmm... okay! First of all, let them relax their guard, and after they get to know you, you will definitely get a promise!'

First of all, it's important in the future.

This is to stop Zerkan from offering Violet a contract marriage.

So, Raphine is trying to get her marriage promise in advance, even if it's a verbal contract.

'Even if it's a verbal contract, if you need a contract marriage partner, you'll think of me first, right?'

「Gorum, gorum.」

'Even if you think it's just a prank you accepted as a child, you'll think you should come back and say no to me before you offer Violet a contract marriage.'

「Is that so?」

'Yes, I will. Because Zerkan was a man with basic manners until he went crazy.'

「Yeah, then... Before that, wouldn't it be important to connect Adrian and Violet?」

In the original story, while returning to the capital, Zerkan and Violet promise to get married.

Around the same time, Adrian decided to propose to Violet....

'If Adrian had proposed to me then, Violet would have accepted it. Violet also wakes up late.'

「Then, can we just stop Zerkan from offering to marry Violet by contract before Adrian's proposal?」

'that's right. That's why I'm trying to get a wedding promise from Zerkan in advance.'

「Make it irresistible, baby!」

'Great! The plan is perfect!'

「Okay! Let's go, baby!」

Raphine, who was clenching her fists and shaking, paused for a moment.

'But what should I do specifically? Can you seduce Zerkan?'

「It's easy. You'll just have to do it as you do for Violet!」

'Come here!'

Acting like her frankly cute and lovely little sister hurt her self-esteem....

I can't help it, though.

Everything is for the sake of peace and cause!

Raphine was determined to stand up from her seat.

"Raphine, where are you going?"

Sophia asked, who was still comforting the duke, who was still in trouble. Raphine answered, pinching her fingers.

"... I want to go to Adrian oppa."

At that, Sophia smiled at Sir Rendell, who was beside her, and asked for Raphine.

"Lady, I'll take you there."

Raphine followed Sir Rendell like that.

Her dad, who was about to collapse, was worried but decided to pretend not to know for now. She'll be fine with her mother by her side.

* * *

As a result of asking users, I met on the way.

Adrian, Violet and Zerkan said that they are now in the library.

Library...?

'It's already a library. They are talented people who will carry the future....'

Of course, the future is cleanly destroyed, but... .

Raphine held her only teddy bear in her arm, and with her short legs she followed Lord Rendell.

"Can I give you a hug?" asked Sir Rendell in the middle, but Raphine refused.

It was because her self-esteem was hurt that she had her arms and legs trembling and hugging her earlier.

When she arrived in front of the library, Lord Rendell opened the door.

Raphine headed to the place she was told by a servant who worked as a librarian. Behind her, Sir Rendell followed quietly.

'There it is!'

Raphine found Zerkan sitting at the table by the window. At that moment, Violet and Adrian were absent.

'It's a chance!'

Raphine ran towards Tudada Zerkan. Lord Rendell stood a few steps away and watched.

"...."

Small and fast footsteps echoed in the quiet library.

Zerkan turned and looked at Raphine.

Raphine was looking up at Zerkan with her wide eyes wide open.

"Hello, Raphine?"

"... Hi."

When Zerkan greeted him first, Raphine responded with embarrassment.

I don't know why he's shy, but strangely, his throat was dry, and his heart was pounding.

Sometimes I felt like my brain was going white. That made it difficult for me to think.

'You need to calm down! That... What did you say? Okay! Just like you do with Violet!'

Raphine came to her senses and reminded her of his purpose again.

'Like Violet....'

「Yeah, just like Violet! Raphine, go!」

"Do you have anything to say to me?"

Zerkan finally closed the book he was reading and looked at Raphine.

Although he might be annoyed by interrupting reading, Zerkan was gentle.

She certainly seemed curious about Raphine because she didn't have a sister.

Raphine just stretched her arm out and looked at it.

"...?"

Zerkan tilted his head, not realizing Raphine's intentions.

'Hug!'

"...."

'Hug it!'

Raphine waved his arm and urged Zerkan.

The most important thing to do with Violet was a hug.

Because Violet always hugged Raphine dearly.

Raphine was smaller than her six-year-old peers because of her slower development.

On the other hand, 10-year-old Violet, Adrian, and Zerkan grew faster than their peers.

Raphine is enough to comfortably hold.

'I'm going to drop my arm....'

Raphine steadfastly waved her arm.

It was meant to be hugged by anyone.

"Hug me!"

'Hug me, prince!'

Ruby, a baby teddy bear who was watching the situation, and even Sir Rendell shouted inwardly.

"Are you asking for a hug?"

"Yes."

When Zerkan barely noticed and asked, Raphine quickly nodded his head.

"...."

After hesitating for a while, Zerkan held Raphine and placed her on her thigh. Raphine hugged Zerkan's neck tightly.

'It smells good.'

It was different from the warm scent I had for Violet, but somehow it had a fresh, clean winter scent.

"... My sister is like this."

Zerkan hugged Raphine as if it was completely awkward.

As Zerkan moved, Raphine, knowing she was about to drop herself, desperately grabbed Zerkan's neck.

Zerkan didn't know what to do, so he held Raphine and stayed still.

Raphine either didn't know what to do with her, and she thought blankly.

'Now what?'

「Like you did with Violet!」

Raphine licked her lips and traced her memory.

Ah!

"Do you have to come back tomorrow?"

Raphine fired her twinkling eyes at Zerkan.

"... Tomorrow?"

"Yes. You have to come back tomorrow, You have to play with me."

"Well, I will come if possible, but...."

"Please! You must come! Please!"

"That, yes...."

To Raphine's enormous pressure, Zerkan replied that she would know without realizing it.

This was the first case.

My head says no, so why are other words coming out of my mouth?

Can a little sister be able to control people? So, Adrian also changed from usual...?

Zerkan blinked in confusion.

Anyway, it looked like I had to come to the duke's house again tomorrow. Because I can't break my promise.

It would have been terrifying for the aide in charge of the Crown Prince's schedule to find out.

"And I...."

"Yes?"

Raphine made a big decision to herself, and said, closing his eyes tightly.

"I am... I'm going to marry Zerkan oppa."

"...."

Yes, it hurts her pride, but from now on, every time she meets Zerkan, she has to breathe out a proposal.

Raphine let out a sigh inside her.

「Life is so tight.... Be strong, baby.」

On the other hand, when he first heard the word 'brother', Zerkan's expression was startled.

'This is a situation I want to show Adrian for some reason...?'

By the way.

"Why do you want to marry me?"

Zerkan asked, handing over Raphine's protruding hair.

He was terribly uncomfortable with having Raphine hanging in his arms, but he couldn't let it go.

It was stuck with so much force, but I was in trouble if I tried to drop it and even cried.

Raphine was her younger sister, barely found by his dear friend Adrian.

She was also much younger than her own half-brother.

She wasn't even close to her brother in the first place, so she didn't have anything to do with her.

Maybe that's why her existence of Raphine felt very new.

She said Raphine was very small and soft. It was warm because of her high body temperature....

Zerkan felt strange because it was the first time she had touched anyone except her mother.

Besides, does she want to get married?

She wasn't her age, and it was the first time she had ever been proposed to by her little boy.
