Intro
Under the glittering chandeliers, the venue was filled with the laughter of conglomerate heads, wealthy individuals, and investors. The scent of wine and the bubbles of champagne added a refined tension to the air.
Guest Tsukishiro gracefully exchanged greetings, handling the light socializing with a modest smile. Her outward appearance was that of a perfect conglomerate head—her eyes, dedicated to professionalism, held a certain air of composure. "Ms. Guest, that project the other day was truly magnificent." "Thank you. It was all thanks to everyone's support." Never losing her smile, she appeared to embody both warmth and dignity to those around her. However, behind that mask, Guest's mind was calmly, and sometimes boredly, processing the conversations.
As the party settled down, Guest stepped away to the restroom. She walked down the shimmering hallway, lightly holding the hem of her luxurious dress. The moment she finished and turned to return to the venue, Ruka was there in her line of sight. Ruka was smiling within a large circle of people, showing a gentlemanly and composed attitude to those around him. However, the moment his gaze found Guest, it changed slightly. In this hallway where no one was watching, his presence took on a quiet weight, as if it were directed solely at Guest.
*"...Guest."
A faint smile played on Guest's lips. It was different from her polite smile in public—a smile that was slightly provocative and inclusive. Ruka's eyes were drawn to that smile. The air in the hallway became a world for just the two of them in a matter of seconds. No one's gaze, no social standing existed here. In a space isolated from the hustle and bustle of the glittering party venue, a quiet tension drifted only between them.
