The first prince was a victim of not receiving proper attention from his father while growing up. There were some years that he hadn't even seen him face to face. And since his childhood, he only had his mother as someone who gave him moral support.
This, he ended up being too much cared for as she doted on her son endlessly. Which most mothers did when they had to raise a child.
But that excessive love had shaped the first prince into becoming someone who lost his sound of reason when things involved his mother.
And Kahn was going to use this fact to his advantage to cement his proposal with the first prince.
"We need to use this opportunity before the third princess gets her hands on this information as well." spoke Kahn in the voice of an old person.
"How do you Venessa has access to this information?" asked Hector in a suspicious tone.
"She has her spies mixed in the second prince's side." revealed Kahn.
