He wouldn't provoke or do anything bad to Luciel anyway because he was Treyton's lover.
Treyton had already said that his lover should always receive what he should receive as long as they were in a relationship.
As Treyton's trusted assistant, he had always been the person who processed Treyton's contracts with his lovers, so he had seen a lot of different people who became Treyton's lovers.
He had always followed Treyton's wishes.
Treyton said that they would be treated as his real lovers, so he respected them as much as he could and always prepared what they needed thoroughly.
He did what he could no matter what their attitude was, as long as Treyton still considered them as his lovers.
It was also the same for Luciel; he treated him with as much respect as he did towards the others.
