Avion was speechless by Alisera's opening up. He didn't realize how much Alisera needed him.
As a princess that was the key to future world domination, she was protected and cared for day and night.
Alisera was only brought to the Trading-Hills Capital to not arouse suspicions as it was tradition for the alliance.
But even then, she had Edora by her side.
Avion was once like her. Spoiled by his power. No one to teach him what is right and what is wrong. He just knows facts from the historical records.
However, there is a difference between them. Avion was forced to learn life lessons the hard way. Meanwhile, Alisera was stuck, abusing her power, and living in comfort.
It was her fault? Yes, certainly. However, if that continued, she would die from accomplishing something.
Humans find happiness in the success they poured effort into. That is undeniable.
