First of all, Princess Xi basically ruled out the possibility that Qiu Tu was simply coveting her beauty.
Just as she had analyzed before: Qiu Tu is a textbook politician.
The heart of a politician is always cold and ruthless. Everything is dictated solely by interests.
As for "lechery," that's just a façade he wears for outsiders.
If he truly were "lustful," he wouldn't have betrayed her so thoroughly after promising to help—and certainly not so completely.
Anyone who's not so sinister and treacherous wouldn't, after breaking a promise, pretend to uphold the contract, then swallow their former partner whole.
This is utterly devoid of political credibility.
Once word gets out, Qiu Tu's political reputation would be ruined, and no one would dare ally with him or make deals.
But! Precisely because Qiu Tu acted so outrageously in this matter, Princess Xi was actually suspicious of his intentions.
