First, Princess Xi basically ruled out the option of Qiu Tu being attracted to her beauty.
As she analyzed before: Qiu Tu is a standard politician.
A politician's heart is always cold and cruel, with everything prioritized for profit.
As for "lustful," it is merely a disguise he presents outwardly.
If he were truly "lustful," he wouldn't have betrayed her so thoroughly after agreeing to her.
You need to know, any less sinister and cunning person would not pretend to continue abiding by an agreement after breaking it and then completely devour the original partner.
This lacks even the most basic political integrity.
Once made public, Qiu Tu's political credibility would be utterly ruined, and no one would dare become his ally or make deals with him.
However, it is precisely because Qiu Tu acted so excessively in this matter that Princess Xi suspects Qiu Tu has other plans.
