The Emperor, A Thousand Years Younger Than Me, Is Obsessed

A thousand-year plan was ruined by a beautiful boy raised in the forest.
In the end, Ariel abandoned the boy.
10 years later. That same boy, Cedric, who harbored a grudge for being abandoned, invades the forest.
And Cedric, in the midst of the blazing fire that burns the forest,
"Let's get married, Ariel."
He proposed.
Ariel, age-1000+@, occupation-great wizard. (Special note: no magic power)
I guess... I need to rewrite my life plan?!
