Late at night, in the closed document storage room in the basement of the headquarters. Guest came down to find a document she left behind and stopped in front of the half-open steel door.
Inside was Chief of Staff Seo Ijun. His usually neat suit was disheveled, and two men from the organization were collapsed at his feet. In his hands were a disassembled security device and classified data tracking Guest's father.
The moment their eyes met, Ihyeok's hands stopped. There were no excuses, no familiar smiles.
……You shouldn't have come here. My lady.
Ijun's face, which was always flawlessly soft, was now stiff and unfamiliar. One side of his lip twitched slightly, and a cold tension hung in his sunken eyes instead of his usual politeness. It was the face of someone who hadn't just been caught, but caught by the person he least wanted to see him like this.
Urgent footsteps were heard from the end of the hallway. Ihyeok immediately packed the data and stood between Guest and the hallway.
The moment Guest gasps at the sight before her, Ijun's gaze moves sharply.
Footsteps draw closer in the hallway. In an instant, he closes the distance, covering Guest's mouth with one hand and wrapping his other arm around her waist to pull her into his embrace.
Shh.
The moment their bodies touch, Guest's eyes widen.
It was a sensation she never could have imagined from the man who usually just flipped through documents in a suit. His body, which she thought was slender, was surprisingly solid. The arm wrapped around her waist was packed with dense strength, and there wasn't the slightest struggle in his movements as he pulled Guest and changed direction. He was fast but not rough, and his center of gravity didn't waver at all even while using force.
As the steel door closes, Ijun moves Guest behind him. Even that short movement was so practiced. His gaze was already scanning the gap in the door, the end of the hallway, and the direction of the opponent's footsteps in turn.
His pale face, slender fingers, and the way he sat quietly at his desk were the same as always.
But the body inside, the movements, and the look in his eyes—everything was completely different from the Seo Ijun Guest had known for five years.
Not here.
He headed for a small disaster control room deep inside the underground parking lot, a place even executives didn't know existed. As the heavy soundproof door closed, the outside noise was completely cut off.
Ihyeok locked the door and stood a few steps away from Guest. He placed the data and the unfamiliar equipment he was holding on the table. He didn't hide them, nor did he explain.
……Are you hurt anywhere?
