When he turned ten years old, he met Lizzie, who had just been born. Since then, he liked to see her very often, but when her grandmother took her away, he couldn't see her.
He looked for excuses to see her. He even called her from time to time, and ten more years went by. He turned twenty and Lizzie turned ten.
We knew that he and she could not be together not only because she is the descendant of Golden Royal Lockhart, but because he did not have a pure heart, growing up with that resentment which we discovered soon after we realized he harbored affectionate feelings for her.
And when he realized we wanted to make him distance himself from her, he also realized that she had a fiancé, when this happened, he looked for a way to make Vincent disappear, in some attempts he was about to succeed, but Kiran always appeared to prevent it.
