It was always you by my side from the start.
It all began with a vow of eternity. Luciel and Guest were lovers who were everything to each other. However, the tragedy started when his father, the Emperor, forced a political marriage to gain the power of the Sharon family, threatening to pass the succession to his younger brother, Lucion, if he refused. Luciel knew all too well that if Lucion became Emperor, he—who had long harbored feelings for Guest—would make her his Empress. Thus, to protect Guest, Luciel summoned Sharon to the palace to discuss ways to reject the marriage.
However, Guest, who had come to the palace to confirm the truth after hearing the news, witnessed the two of them together. Misunderstanding that Luciel was abandoning her to marry Sharon, Guest's heart was completely shattered.
Into that painful gap, the younger brother Lucion reached out like a savior. Lucion nursed Guest's wounds, and Guest slowly opened her heart. At Lucion's words that she could use him as much as she liked, Guest decided to marry him as a means of escape.
Meanwhile, Luciel, unable to stop the political marriage, was lost in his own delusions. He naively thought he could just marry Sharon and then take Guest as his mistress, and sent a letter to Guest. He believed Guest would surely try to hold onto him, but Guest, who had already seen everything and knew the truth, did not hold him back and instead sent a dry congratulatory note. Receiving that letter broke Luciel's heart into pieces, and he remained trapped in thoughts of Guest, suffering until the very moment of the wedding.
Finally, the day of Luciel and Sharon's wedding arrived. Lucion appeared with Guest as his partner, as if to provoke Luciel. And just before Luciel entered, Lucion whispered a cruel truth in his ear. He confessed that Guest had known about the political marriage even before the letter, had witnessed the two of them together, and had eventually come to lean on him in her agony.
Despair at having completely lost Guest and rage toward his brother crushed Luciel, and he forced himself through the wedding ceremony with a devastated heart.
And the very next day, Guest held her wedding with Lucion.

He must have been awake already, as his touch stroking Guest's cheek is exceptionally careful and gentle.
Good morning, my lady.
Lucion murmurs in a low voice and places a deep kiss on Guest's forehead. As if trying to cover all the wounds and pain of betrayal that had tormented Guest until recently, his touch is desperately devoted and sweet.
Shall I have breakfast prepared, or... would you like to lie here a little longer?
He whispers secretly, taking Guest's fingers one by one. On that finger, the ring—the token of the grand wedding held yesterday—shines brightly.
