Im a bit confused

Im not sure on where the annoyance is coming from teach but you do have to understand that hes not in a normal situation, hes "dating" a guy who killed his father and the doc and now a guy who was falling (im assuming he was the guy who took the shot to deliberately kill him) he dissociates as a way to cope and process explaining his emotionless face alot of the times. He isn't used to death and thats what makes him opposite of guwon. Teach isn't used to seeing people die infront of him it's just apart of his humanity, if he didn't have his humanity he would be like guwon. Hopefully the story doesn't go down the rail cuz i do find the story interesting...
