Ok, so I've gone back to chapter 1 after chapter 23, and honestly dont think the man Guwon killed was Teach's dad. The guy in the Grey shirt and blue jeans walked into Teach's house after he was already wounded and on the floor. It looked like Grey shirt guy was planning to rob Teach or do somthing else, and Guwon came in and killed Grey shirt by bashing him over the head. I don't think Guwon killed Teach's dad, but that looks like the misunderstanding route we're gonna go down.
