As for the rest of what Zayen said…
Caused by accidents.
Compelled by circumstances.
Not personal?
Thales narrowed his eyes and looked at Zayen who was trying his best to restrain himself, but the words of the Duke of Western Desert rang in his ears:
"Before you accept their kind offer, please remember: they are only doing it because they oppose your father, not because they are genuinely loyal to you."
"Oh, is that so?" Thales asked coldly.
"So what you're telling me is, six years ago, the fact that you lent Vine Manor to Serena was 'caused by accidents'?"
"And you were 'compelled by circumstances' when you, after saying some kind words to me, let the Night Queen come after me?"
Zayen's expression started to turn unpleasant.
"What a coincidence," Thales adjusted his posture and sneered, "Do you know what life lesson Lady Serena, who found me thanks to you, taught me?"
