Thomas is leader of the top guild in USA. Very prideful and was (possibly) the most powerful guy in the world before Jinwoo came along. He told his underling to stay away from Jinwoo but also told Jinwoo to stay away from his underling. Underling instead kidnapped Jinwoo's buddy to provoke Jinwoo and get Thomas to intervene. Neither Thomas nor Jinwoo plan to back down, so instead they butt heads. Make sense?
What does Thomas have to do with Jinwoo? Is it because of his dad? The other Korean guy under his guild? Or just for the plot? I'm kinda confused right now. It doesn't even look like Jinwoo did anything to him. Did the Manhwa gloss over something important in the novel?
