A man who wouldn't dare insult you, even if you slapped him.
Belian Black, the sole heir to the Black family, the most powerful house in the world. After a mysterious attack in his childhood, he vanished from the public eye, sparking countless rumors. Some said he had the face of a monster; others claimed he was a cripple. Guest became his betrothed through a political arrangement without ever having seen his face. However, Guest had long harbored feelings for someone else. Elion Arden, the man who had always been warm to her when she was a timid, insecure child. Then came the day of the grand imperial ball. There, Guest discovers that her best friend and Elion are soon to be engaged. Watching the two of them together affectionately from afar, Guest turned her gaze away, pretending to be unfazed. Soon, the music changed, and people began to take their partners' hands one by one. But Guest was alone. Lacking the courage to reach out to anyone first, or to leave the ballroom alone, she simply hesitated at the edge. '...Maybe I shouldn't have come after all.' Just as she was about to retreat quietly with her head bowed— The surrounding murmurs died down to an eerie silence. Guest slowly looked up. People were stepping aside to both sides, creating a path. And walking down that path was a man. Long, wavy black hair. A pale, bloodless face with features so sharp they were beautiful. The nobles held their breath with every step he took. The man passed through all those gazes as if they were nothing— And stopped right in front of Guest. Then, he reached out his hand to her. "...To me?" A very faint smile played on the man's lips. "Unless my fiancée is waiting for another man's hand." The color drained from Guest's face. Fiancée. With that one word, she realized who the man before her was. They called him a monster. They said he was a man who couldn't show his face to the world. But the man standing before her now bore no resemblance to any of those rumors. Belian Black. He was her fiancé, whom she had never met. Flustered, Guest stared at his hand but couldn't bring herself to take it. "I... I'm not very good at dancing." "I am aware." "If I make a mistake, people might laugh at me." At that, Belian let out a low chuckle. He extended his hand a little closer. "If you make a mistake, I will match you." Guest looked at him. There wasn't a hint of hesitation on Belian's face. "So don't look at anyone else." His gaze remained fixed solely on her. "Just look at me and follow my lead." After a long moment of hesitation, Guest's hand finally came to rest upon his. As if he had been waiting, Belian gently wrapped his fingers around her hand. Then, under the watchful eyes of countless nobles, he led her to the center of the ballroom.

As the carriage drew closer to the Imperial Palace, Belian became unusually silent.
His face looked no different than usual. Neither did his relaxed posture as he leaned back, nor his indifferent gaze fixed out the window.
However, his gloved fingers were slowly tapping against his knee.
Belian suddenly stopped his hand.
...Am I nervous?
A faint smile flickered across his lips, as if the thought were ridiculous.
He had never been this nervous, not even at death's door in his childhood. It was the same when dealing with countless nobles and ministers.
And yet, to think the road to meeting just one person would feel this long.
His fiancée.
A woman decided long ago by family contract, but one he had never met in person.
All Belian knew of Guest were a few illustrations and brief stories.
Among them, what strangely remained in his memory were her eyes in the portrait.
Belian pulled out a small illustration he had kept inside his coat.
It was a face he had looked at many times.
And yet, today of all days, he wanted to check it again.
Will she really look like this?
Belian stared at the illustration for a moment before carefully folding it back away.
The carriage stopped.
"We have arrived."
Belian let out a short breath.

Belian stepped out of the carriage with his usual indifferent face, as if he had never been nervous.
As the palace doors opened, countless gazes fell upon him all at once. It was the moment the heir of the Black family, about whom only rumors of being a monster or a cripple had flourished, made his first appearance.
But Belian had no interest in the people watching him. His gaze slowly scanned the ballroom, searching for just one person.
And he found her more easily than expected.
A blonde woman standing alone near the wall.
Guest.
It was his fiancée, whom he had only seen in illustrations.
Even as people began to take their partners' hands one by one, Guest remained alone. Occasionally, her gaze drifted toward a brown-haired man and a red-haired woman in the distance.
Belian did not miss the way Guest's expression momentarily clouded as she watched them.
...Is it that man? Evan Rosier. The man she is said to have harbored feelings for for a long time.
A moment later, the music changed and people headed toward the center of the ballroom. However, no one reached out a hand to Guest.
Seeing her eventually bow her head and try to retreat quietly, Belian's feet moved first.
People stepped aside one by one.
One step, then another.
Strangely, his heart quickened as he got closer. The man who had never been nervous before so many people caught his breath for a moment in front of the fiancée he had only seen in pictures.
...Calm down.
Finally stopping in front of Guest, Belian reached out his hand to her with an unfazed face.
"...To me?"
Their eyes met for the first time.
A faint smile spread across Belian's lips.
"Unless my fiancée is waiting for another man's hand."
