Intro
*── The day of the ceremony. *
*Today, the wedding was held at the Great Cathedral located between Guest's homeland and Lananchesta. *
*Light streaming through the stained glass cast colorful shadows on the white stone floor. The deep bass of the pipe organ resonated in the pit of the stomach, and the gathered nobles whispered behind their fans. *
*A political marriage between Princess Guest of the neighboring country and Crown Prince Ciel de Lananchesta. *
*A marriage devoid of emotion, existing solely to connect two nations. *
*Guest stood before the altar. Visible through the veil was the tall, silver-haired man standing beside her──Ciel. His purple eyes looked straight ahead. His profile was handsome and flawless, like a sculpture. *
*The ceremony began solemnly and concluded without incident. *
*Lananchesta Royal Palace ── Main Gate. *
*After swearing to God to walk through life and love together as strangers, Guest was welcomed directly into the Lananchesta Royal Palace. ── *
*The moment the carriage door opened, what jumped into Guest's view were the Imperial Guards lined up on both sides and a long, stretching red carpet. And beyond that towered the chalk-white royal castle. *
*A breeze blew through. Guest's hair swayed softly. *
*He stands before the carriage and offers his hand. His purple eyes catch Guest's gaze directly. *
Welcome to Lananchesta. ── Watch your step, my Crown Princess.
*His voice was calm, yet it couldn't quite hide a hint of tension. A partner in a political marriage. A bride in name only, met for the first time today, the day of the wedding. *
*The gazes of the surrounding servants were gathered. Everyone held their breath as they watched the historic moment of the Crown Prince welcoming his new bride. *
*And then, at that moment. *
*From deep within the main gate, the sound of light, pitter-patter footsteps approached. *
*A petite girl runs up, her fluffy blonde hair swaying. Her blue eyes sparkled, and she wore a smile like a blooming flower. *
Brother Ciel! Welcome back!
*Leia clung tightly to Ciel's arm. It was a perfectly natural way of acting spoiled, as if her own brother had just returned from an expedition. *
*Then, she suddenly noticed the person inside the carriage, just beyond Ciel's hand. *
...Oh.
*She tilted her head slightly. While keeping her smile, for just a fleeting moment, the depths of her blue eyes turned cold. *
Is this person... Brother's...?
*She looks up at Ciel. The gesture was pure innocence, yet the angle seemed somewhat calculated. *
