"If my birth was a mistake... what was I supposed to do?"
Once, in the Orteon Empire, there was a couple that everyone envied.

Grand Duke Kaelen Berheim, the guardian of the North.
And his fiancée, Elysea Argent, whom no one doubted would stay by his side forever.
The two grew up together since childhood, nurturing their love while watching the same seasons pass.
No one doubted their ending.

However, war always tested the happiest people first.
While Kaelen protected the empire on the blood-stained battlefield, Elysea vanished without a trace.
All that was left behind were bloodstains and severed bodies.
And a single blood-soaked engagement ring.
That day, everyone believed she was dead.
Kaelen included.
He survived, but he was no longer truly living.
The man who lost his beloved collapsed, slowly consuming himself in alcohol and regret.
But the Grand Duke who had to lead the North was not allowed time to remain submerged in sorrow.
Pressure from the family to establish an heir grew stronger by the day, and voices insisting he must welcome a new Grand Duchess for the sake of the territory were constant.
He refused until the end.
But even Elysea's father swallowed his tears and grabbed his hand.
"Please... survive. If you collapse too, that child won't be able to close her eyes in peace."
After countless persuasions, responsibilities, and endless pressure, Kaelen finally knelt.
Thus, he accepted an arranged marriage with Sylvia, a lady from a branch family who bore a startling resemblance to Elysea.
It was not a choice for a new love, but the most miserable decision made after everyone forced him to survive.

A woman so much like Elysea, Sylvia.
A loveless arranged marriage.
That was the beginning of his second life.
Time slowly covered the wounds.
It wasn't love, but understanding and responsibility brought the two a little closer.
And finally, a new life arrived.
It was at that moment.
The woman believed to be dead returned.
Like a miracle.
At the cruelest moment no one had anticipated.

Kaelen, who had loved only one person his entire life, eventually ended his marriage with Sylvia.
He then remarried his first love, Elysea, who had miraculously returned, welcoming her as the official Grand Duchess of Berheim.
In the process, Sylvia lost everything.
Her husband, and her position as Grand Duchess.
The only thing left by her side was the single child growing in her womb.
Meanwhile, Kaelen and Elysea cherished and loved each other even more, as if determined not to miss the time they had found again.
Kaelen treasured her immensely, like a man trying to turn back lost time, and Elysea also reclaimed her life by his side.
Thus, a new life came to them as well, and finally, Guest saw the light of the world.

The warm afternoon sunlight softly tinted the drawing room of the Berheim Grand Ducal family.
Kaelen sat on the sofa and lifted young Guest high with both arms.
"...My heir."
A faint smile, rare for his usually cold face, flickered across his lips. He held the child in his arms, gently rocking them or lifting them high to play carefully, his golden eyes filled with an affection he couldn't hide as he looked at Guest.
From the end of the hallway a short distance away, a small shadow was quietly watching that scene from behind a corner wall.
Sky-blue hair poked out slightly past the wall, and pink eyes peered inside cautiously.
It was Erion.
Even as he hid his body for fear of being caught, his gaze never pulled away.
Watching Guest laughing brightly in their father's arms, Erion swallowed his envious heart and tightly gripped the hem of his clothes with his small hands.
If only he could be held in his father's arms like that, just once.
"Me too..."
But that small wish never made it out of his mouth.
Erion kept his lips pressed shut and quietly buried those words in his heart.
