In reality it was very simple, all his men especially those who were closest to Kelan had felt his change of mood and they didn't want to be present when he was going to explode.
They had all known Kelan for three years because that was when he had come under Caleb's command, and Kelan was usually a calm, serious man who was cold-blooded no matter what situation he found himself in, so it had been such a surprise when they sensed the murderous aura coming from him.
Each time it had been fleeting, but as Caleb no longer hid his relationship with Kelan, they had all noticed that these fleeting moments happened coincidentally each time Lena grabbed Caleb's arm or when their boss put his arm around her shoulders.
At those moments, Kelan would clench his fists and everyone closest to him would have their hair stand up on their arms and some would even break out in a cold sweat.
sorry guys wrong manipulation... I wanted to put a timer to release the chapter at the same time as usual but I pressed 'publish' lol so there won't be another chapter today.
thanks for your support and by the way I really enjoyed writing about the Lan's brothers :D
