No matter how lacking a father I was, my heart was sincere when I called you my son.
Once, in the Orteon Empire, there was a couple that everyone envied.

Archduke Kaelen Berheim, the guardian of the North.
And his fiancé, Guest, whom everyone believed would stay by his side forever.
Having grown up together since childhood, the two nurtured 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, Guest vanished without a trace.
All that was left behind were bloodstains, dismembered remains...
And a single blood-soaked engagement ring.
That day, everyone believed in her death.
Kaelen included.
He survived, but he was no longer a living man.
The man who lost his beloved collapsed, slowly consuming himself in alcohol and regret.
But the Archduke, who had to lead the North, was not allowed time to simply wallow in sorrow.
The family's pressure to establish an heir grew stronger by the day, and voices insisting he welcome a new Archduchess for the sake of the territory were incessant.
He refused until the end.
However, even Guest's father eventually held his hand while swallowing his tears.
"Please... stay alive. 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 a political marriage with Sylvia, a young lady from a branch family who looked remarkably like Guest.
It was not a choice for a new love, but the most miserable decision made after everyone forced him to survive.

A woman who looked so much like Guest, Sylvia.
A political marriage without love.
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 miraculously returned first love, Guest, welcoming her as the official Archduchess of Berheim.
In that process, Sylvia lost everything.
Her husband, and her position as Archduchess.
The only thing left by her side was the child growing in her womb.
Meanwhile, Kaelen and Guest cherished and loved each other even more, as if determined not to miss the time they had found again.
Kaelen treasured her intensely, like a man trying to turn back the lost time, and Guest also regained her life by his side.
Thus, a new life came to the two of them as well, and finally, Lior saw the light of the world.

It was an afternoon when the warm sunlight was softly coloring the garden.
"Kyah!"
Clear, innocent laughter spread throughout the garden.
Lior, held in Guest's arms, waved his small hands in the air and squealed repeatedly, and a natural smile spread across Guest's lips at the lovely sight.
Watching them, Kaelen let out a small chuckle and slowly approached.
"Come here."
With a tender voice, he reached out toward Guest.
"Mom is heavy. Our Lio, shall you come to Daddy now?"
It was a soft smile that didn't rush or pressure the child. A gesture where the kindness of prioritizing Guest naturally seeped through.
From a short distance away, Erion watched that peaceful scene in silence.
His hair fluttered quietly in the wind. His gaze remained fixed on Lior laughing brightly in Guest's arms and Kaelen reaching out tenderly.
Erion's eyes were calm as he watched the scene without a word. However, in their depths, complex emotions that no one could easily read were gently rippling.
"I also..."
Those words were never finished.
Erion simply watched the three happy-looking people from afar. Unable to voice his wish that he could be inside that circle with them just like that.
