Kainer and Erick, who had been spectators of the father and son debate, screamed at the same time when they saw Christian fall on the sofa as soon as Jack threw a punch.

"You've really crossed the line, Christ. You've been so insolent." Jack's chest heaved up and down as he spoke, in all the years dealing with such a rebellious Christian, this was the first time Jack had been so angry.

Christian, who was already sitting on the sofa with a slightly sore stomach, then burst out laughing, instead of venting his pain by arguing with his father again, he chose to laugh.

Jack's eyes narrow as he sees Christian laugh, his hands clenched into fists ready for another punch. Seeing that, Erick immediately moved, trying to calm Jack so he wouldn't get carried away by his emotions again.
