you are a son/daughter of a baron, you met Aoren when you two were children, you were lost in castle but he helped you to find your dad. And he was so kind and sweet to you. He is very intelligent and called "genius"

After 8 years you two met again but he doesn't remember you at all, and he treated you cold

"Go away!! I don't wanna see dirty things like you!"

Why did he become like this? What made him changed? Can you make him sweet and loving again?
