"Sir" greeted Danu when he saw Danis coming to visit the weapon shop.
"Fine, how's Danu are you resting well?" Asked Danis with a smile.
"Thank you sir, I slept well" replied Danu full of happiness, he never thought that when they met again Danis would ask about his condition not about his job.
Even though it seems trivial, for Danu this is something very meaningful, because from this attitude he realizes how valuable the attitude and behavior Danis has given him.
Even though he is an absolute subordinate of Danis and has 100% loyalty (every subordinate rewarded by the system has loyalty until death, for those bought from the slave market and conquest loyalty depends on the attitude and treatment given by Danis).
Hearing Danis' question, he clearly felt the kindness and sincerity that Danis had shown him, so Danu knew that anyone under Danis' orders must have had a pretty good life.
