The wives of the two ice princes

Not yet. The current story briefly introduces the Seven Princes, but it doesn't have a character profile like in novels and manhwa, which will make it less professional.
I recommend that you include a page at the beginning of the novel titled ✦ Characters ✦, for example:
👑 The Imperial Family
👑 Emperor Kim Seong, the ruler of the empire, is strict, puts the kingdom’s interests above all else, and hides ancient secrets from his sons.
🤍 Crown Prince Kim Jin is quiet, wise, and it is difficult to know what he is thinking. He is nicknamed "The White Prince".
🖤 ​​Prince Min Yoongi (Suga), the head of intelligence, is mysterious, intelligent, trusts no one, and knows everyone's secrets.
📚 Prince Kim Namjoon is the genius of the empire and its advisor, and he loves books and planning.
⚔️ Prince Jung Hoseok, the commander of the Royal Cavalry, is cheerful outside of battles, and terrifying within them.
🎭 Prince Park Jimin is the most popular prince, tactful and skilled at hiding his feelings.

The final chapter: The truth that changed everything
The flames were rapidly engulfing the corridors of the wing.
You tried to open the door again and again, but it was locked tight.
Outside, the guards were trying to break down the door, but the fire was preventing them from getting closer.
Jungkook shouted:
"Get away!"
Then he drew his sword and struck the door with all his might until it shattered.
He rushed inside, not caring about the flames, and when he saw you, he took your hand and covered you with his cloak before taking you outside.
On the other side, Tae had rescued Lisa from a room filled with smoke.
As soon as everyone had left, a large part of the wing collapsed.
Silence prevailed...
Then Shawqa said, looking at the burning door:
"This was not an accident."
The emperor looked at him sharply.
"Do you have any proof?"
Shawqi took out a letter with burnt edges and said:
"I found her before the fire started. The goal was to kill my wife Jungkook and Tae."
The ministers began whispering, while the seven brothers stood in a single line.
Jane stepped forward and said:
"It will no longer be hidden."
After a lengthy investigation, it was discovered that the chief minister had been plotting for years to stir up trouble within the imperial family, believing that getting rid of the princes’ wives would make the brothers turn on each other.
He and his accomplices were arrested, and the plot that terrified the palace came to an end.
...
That night, Jungkook stood in front of you in the garden.
He remained silent for a moment, then said:
"On our wedding day, I distanced myself from you because I knew there was a conspiracy within the palace. I thought that my distancing myself would protect you, but today I realized that I was hurting you more than protecting you."
You lowered your head and did not answer.
He finished in a quiet voice:
"Will you give me a chance to be the husband I promised you?"
You smiled for the first time since entering the palace, and nodded your head.
On the other side, Tae sat with Lisa inside his studio.
He said, looking at a new painting:
"I always used to draw a gray sky... but since you came into my life, I want to learn to draw colors."
Lisa laughed and replied:
"Then I will be the first to see your colorful painting."
Tae smiled, and it was the first genuine smile in a long time.
...
Months passed, and the palace changed.
You began to participate with Jungkook in military affairs, while Lisa helped Tae set up art exhibitions whose proceeds went to the poor.
As for the other brothers, they have begun to treat you both as part of the family.
Jane was asking for your opinion on some issues.
And Shawqi, despite his coldness, began to trust you both and share with you

Wonderful! So we'll write it as a real novel. 🌹
Novel: The Forgotten Princesses
Chapter One: The Beginning of the Nightmare
The Aurelia Empire was the greatest empire on the continent, ruled by Emperor Kim Seong, a man who was famous for his justice before his people, and his cruelty within his palace.
He had seven sons, who became famous throughout all the kingdoms.
Prince Jin, the Crown Prince, is calm and wise, but no one can know what is going on in his mind.
Prince Shuga, the intelligence officer, is a mysterious man who rarely smiles and knows everyone's secrets.
Prince Namjoon, the Minister of Science and Strategy, is so intelligent that ministers were afraid to discuss things with him.
Prince Hoseok, the commander of the royal knights, is kind to people, but strict in his work.
Prince Jimin, the people's favorite, always smiles, but his smile hides a lot.
Prince Taehyung, a lover of drawing and music, disliked restrictions and rejected the idea of ​​marriage.
Prince Jungkook, the youngest of the princes, commander of the Imperial Army, the strongest swordsman in the kingdom, cold-hearted and distrustful of everyone.
...
As for you, you were the eldest daughter of the Duke of the North, a smart and quiet girl who loved reading and horsemanship.
Your younger sister Lisa was quite different; cheerful, stubborn, and outspoken, unafraid to speak the truth.
You both grew up together in your father’s palace, and you never imagined that your fate would be linked to the imperial family.
The story began when you met Jungkook at the Spring Festival.
A wild horse was running among the people, and before it reached you, Jungkook grabbed its reins and saved you.
You talked many times after that, until you both fell in love with each other.
As for Lisa, she met Taehyung at an art exhibition, and loved him because of his kindness and calmness.
And after a whole year...
Prince Jungkook's marriage to you has been announced, as has Prince Taehyung's marriage to Lisa.
The whole kingdom was celebrating.
but...
On the wedding night...
After the ceremony ended, Jungkook entered his suite, took off his military cloak, and then said without looking at you:
"Don't expect me to be a perfect husband."
I was shocked.
You said calmly:
"But... wasn't this a marriage based on love?"
He answered as he headed towards the door:
"He was."
Then he left.
And in the adjacent wing...
Lisa was smiling as she looked at Tae.
But Tai said, looking at his paintings:
"Marriage changed everything... I want some distance."
Lisa's smile disappeared.
And the following morning...
The two princesses sat down at the breakfast table for the first time.
All seven princes were there.
but...
Jungkook never looked at you even once.
