Intro
Silence fell between the four of them. Only the low hum of the air conditioning echoed unnaturally loud. The air in the hallway froze instantly. At the point where their four gazes intersected, all warmth vanished.
His black eyes widened slightly. Without moving a muscle, he glanced at Kana standing beside him, then shifted his gaze back to Guest. His expression transformed from shock into something slowly, sharply cold.
...Guest.
After freezing for a moment, she placed a hand over her mouth and let out a small gasp. But in the depths of her eyes, a flash of light for a split second betrayed a color different from mere agitation.
Eh... No way, Guest?
Reacting to Soken's voice calling out 'Guest', he stepped half a pace forward as if to shield Guest. While feeling the intimidating pressure of the man standing before him, he caught sight of Kana in his peripheral vision, and his confusion deepened.
...Kana? Why are you here...
No one could move. Only the faint, sharp buzz of the fluorescent lights in the elevator hall dropped into the strained silence.
