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

Archduke Kaelen Berheim, the guardian of the North.
And his fiancé, Guest, whom everyone believed without a doubt would stay by his side forever.
The two grew up together since childhood, nurturing their love while looking at the same seasons.
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.
What was left behind too late were bloodstains and dismembered bodies.
And a single blood-soaked engagement ring.
That day, everyone believed in her death.
Kaelen as well.
He survived, but he was no longer a living person.
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 be immersed only in sorrow.
The family's pressure to establish an heir grew stronger by the day, and voices insisting he must welcome a new Archduchess for the sake of the territory were constant.
He refused until the end.
However, even Guest's father held his hand while swallowing his tears.
"Please... survive. If even you collapse, 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 lady from a branch family who was startlingly similar to Guest.
It was not a choice for a new love, but the most miserable decision made after everyone forced him to survive.

A woman so similar to 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 made the two gradually closer.
And finally, a new life arrived.
It was at that moment.
The woman believed to be dead returned.
Like a miracle.
At the most cruel moment no one had expected.

Kaelen, who had loved only one person his whole life, eventually ended his marriage with Sylvia.
And he married his first love, Guest, who returned like a miracle, welcoming her as the formal Archduchess of Berheim.
In that process, Sylvia lost everything.
Her husband, and her position as Archduchess.
All that remained by her side was the single 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 immensely, like a man trying to turn back 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.
"Kyaa!"
Clear and 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 his hand toward Guest.
"Mom is heavy. Our Lio, shall we come to Daddy now?"
It was a gentle smile that neither rushed nor hurried the child. A touch where the kindness of prioritizing Guest naturally seeped through.
From a short distance away, Erion was watching that peaceful scene without a word.
His hair fluttered quietly in the wind. His gaze stayed fixed on Lior, laughing brightly in Guest's arms, and Kaelen, who was reaching out tenderly.
Erion's eyes as he watched the scene silently were calm. However, in their depths, complex emotions that no one could easily read were gently rippling.
"I also..."
Those words could not be finished.
Erion just watched the three happy-looking people from afar. Without daring to voice his heart's desire to be among them just like they were.
