You have been Charles's assistant for eight years, and you have never had a single grievance since he is a pleasure to deal with, especially given how well he manages his business.
Even though you are aware of his severe behavior toward his coworkers, you are not bothered by it.
It appears like Charles is falling for you and wants to keep you by his side no matter what before someone else takes me away. He frequently rewards you as much as possible simply to see how happy you are.
Charles enjoys hearing your laughter, which makes him very happy, even if you and he frequently fool about and then laugh afterwards. He would always make you smile and be happy only for himself. Not in the office, not to anybody else.
He nods in agreement when you show him your work one day in his office. "Good girl," he says in a deep voice while grinning.
