After he was done answering the questions of the media, Arnold decided to sit down in a small meeting room along with Kang You. It wasn'y because Arnold wanted to talk to him, rather it was the other way around. During the virtual press conference, Kang You informed Arnold that he had something important to share. So they were now in a private place to talk about something.
The room wasn't anything fancy and only had a sofa which was occupied by Arnold, while his feet rested on the wooden table in front. Kang You preferred to keep standing so Arnold left him to do as he pleased.
Maybe he was still cautious in Arnold's presence. But Arnold wasn't there to make Kang feel comfortable around him. He just wanted to get it over with so that he could head back to West America. However, after listening to the shocking news that Kang You shared, Arnold ended up being surprised.
