Things that transpired between them were so clear from the very beginning. Cane had never forced her to stay. She was free to live her life. Right after they were freed from the slavery, the alpha had given her a choice and she insisted on staying, which gave her the position of the mistress right now.
"I will give you the same choice again now." Cane had never tried to deceive Aria, he had emphasized the same from the very beginning. "You can stay or leave. I will give you a house in a place that you want and you don't need to think about money. I will take care of you."
What he offered sounded very generous, but compared to what she had done for him, during their slavery, it was only a small amount of gratitude that Cane could offer to people who always stood by him.
