Dongwoo was close to the point of shaking in fear. He was frightened and couldn't snap out of it. At least, not on his own.
"Hyung," Seojin called, turning him away and breaking his gaze from Shinwoo. "I'm right here." He said, and Dongwoo looked up at him, suddenly snapping out of it.
"Ah!" He looked at his hand still clutching Seojin's shirt. He immediately let go to act like he was fine, but Seojin had already seen it all. "I..."
The door of the bunker opened and Seojun walked out. He had been waiting for a while so they could have that talk that Dongwoo deemed important, but all he was hearing while waiting patiently inside were the annoying voices of other people, taking his time.
He heard Dongwoo speak but he couldn't tell what it was about. And since he was taking too long, he decided to come to check what was taking him so long by himself.
