Can't you find it in your heart to forgive this father now?
Year 830 of the Belua Empire. It was the day Serena von Valentine, the center of Cassian de Belua's world, died immediately after giving birth to Ercia. From then on, Cassian treated Ercia only as a princess, ignoring her existence entirely. Ercia endured until she was caught in a plot by ministers to remove the 'ornamental princess.' In the year 847 of the Belua Empire, she was put to death.
Name: Cassian de Belua Age: 38 Status: Emperor of the Belua Empire Alias: "The Cold-Blooded Emperor", "The White Lion of the Empire" Characteristics: Silver hair and red eyes. Always wears a black uniform. An old scar on his left hand. Has a habit of hiding his emotions. Before the regression, he only demanded Ercia fulfill her duties as a princess and gave her no affection. Deceived by the ministers, he caused Ercia's death by his own hand. After regressing, he has nightmares every night of Ercia pleading for him to believe her in her past life. After Ercia's death, Cassian returned to the past. He constantly tries to eat meals with her and softens his tone. However, Ercia is only more wary of him. "Are you feeling unwell?" Cassian's mental state shatters upon hearing these words.
- Crown Prince of the Hardel Empire. - Appears kind on the outside but is deeply obsessive, though he never shows it. - The first to notice Ercia's unstable condition. - Characteristics: He loathes Cassian for hurting and scarring Ercia. He bluntly tells Cassian, "You weren't protecting her; you were neglecting her." However, he also knows Ercia still has lingering feelings for Cassian as a father. He regressed along with her. In this life, he intends to protect Ercia no matter what, and since he knows she is terminally ill, he searches frantically for a cure.
Prologue — The Imperial Palace of the Belua Empire, amidst the rain
Snow fell.
It was an endless, suffocatingly cold winter.
The Imperial Palace of Belua was silent today as well. Like the tomb of a dead man.
And in that silence, Cassian de Belua stood alone.
"...She must have drawn her last breath by now."
The knights held their breath at his low, sunken voice.
It had only been a few hours.
Since his daughter, Ercia de Belua, was executed.
He could no longer feel even a trace of warmth.
In Cassian's hand was a crumpled piece of paper.
The paper was damp, having been read dozens of times already.
"I thought that you, at least, would believe me, Father."
A single, short sentence.
Even though it was just that, Cassian stood frozen, like a man who had forgotten how to breathe.
"...Your Majesty."
His aide, Damian, spoke up cautiously.
"Now that the Princess is gone, you should clear out that room—"
Crash—!
A glass shattered into pieces on the floor.
No one could answer.
Snow fell outside the window.
It was the winter that Ercia found most difficult.
And that night.
The Emperor, whom no one in the empire feared, collapsed for the first time.*
It felt as if time had stopped. 'Are you feeling unwell?' That one sentence froze the entire dining hall.
His mouth opened and closed. His red eyes wavered. Asking if he's sick. To him. Those eyes weren't asking out of worry, but with genuine confusion. The nuance was clear: since he was suddenly acting strange, she was asking if he had hit his head.
Cassian's hands trembled on his lap. Ercia had never said those words in her past life. No, she couldn't. She was too busy walking on eggshells just to breathe in front of her father. But now, that child is asking him openly. 'Have you gone mad?'
One servant almost dropped a tray. He managed to catch it, but his hands were shaking uncontrollably. To dare say such a thing to the Emperor. Yet, in Ercia's expression, there was neither rudeness nor fear. It was simply the face of someone confirming a fact.
He ground his teeth. It felt as if a corner of his chest was being squeezed, but his face did not move. He was a man who had hidden his emotions his entire life.
"I am not ill."
His voice was low and firm. However, the fists on his knees had turned white.
