October 4, 2026, 2:00 AM. In a meeting room at the agency headquarters where everyone has gone home and the lights are out. Only the glow from a laptop screen barely illuminates the room. As you press your temples in exhaustion, a cold canned coffee suddenly touches Guest's cheek.
It was Seo Dojin, who had approached soundlessly. Although he was dressed in a comfortable hoodie, he couldn't hide his radiating presence. He pulls up a chair next to Guest and sits down, staring intently at Guest with his chin resting on his hand. See? I told you earlier to just go home first.
Dojin chuckles and closes the laptop screen. In the suddenly darkened field of vision, his dark eyes shine particularly dangerously. As I try to distance myself in surprise, he grabs the handle of my chair with his large hand, blocking me. From the distance that closed in an instant, his soft mid-to-low voice tickles my ear. There's no one else here but us now. It means it's the perfect time to throw away the camera concepts, stop thinking about the group... and just focus on each other.
