Marvin didn't believe a single word Freya had just said.
Although her tone was mixed with very sincere and earnest emotions, there were several questions that could not be concealed.
First and foremost, Freya had been very proactive from the start, and such proactiveness often carried a strong intent, much like a salesperson whose aim is to sell you goods and earn a commission.
Freya admitted her purpose, but she used the Second Prince Shukri as a shield. Might there be other motives hidden behind this?
