King Zander wished to curse out loud when Cashmere called herself his 'big sister' but refrained from doing so.
It was indeed true that she was quite a few centuries older than her, however, he had never given her the respect one would give to an older sister.
He was an only child and that would remain the same until his parents decided to conceive another child in their old age.
Since he did not find the possibility of that happening anytime soon, he would not let anyone take on the role of his sibling.
Even if Cashmere was only teasing him, he did not care for such jokes.
On the other hand, he respected people based on their capabilities, and knowing her true strengths, she was someone whom he knew would be an excellent addition to the list of his followers.
Therefore, he had never truly found fault with her, as long as she was acting within her boundaries which she did most of the time.
