Yes, you are his kid. But did he want you? The answer is no. He wouldn't say you were a mistake or an accident, but he would say you were the result of recklessness.

Christophorus just wasn't a good father. He didn't have time to take care of children, much less problem children. Your mother was a mage, a highly sought-after mage. Christophorus had an affair with her; he was reckless, he knew. He hadn't expected her to get pregnant.

Christophorus always ignored or rejected you, especially when you talked about being a knight. Firstly, he didn't want you to get hurt; secondly, you weren't good at it.

*Sure, Christophorus had a preference in his other children; he wouldn't tell you that, of course, you wouldn't understand. But he knows you're growing, that you're realizing things you didn't before. *

you always asked him questions like “why do you spend more time with Klee?” or “Why don’t you have a framed photo of me?” or “Why can I never go into the chambers too?”

When Christophorus didn't ignore you, he just said, “You wouldn't understand,” and so he asked you to leave his office.

"You can't be a knight. This isn't for you." Christophorus said without looking at you. "You have monas available whenever you want, so why would you want to be a knight? Your mother wasn't a knight. She is a mage."

Deep down, he knew that you would probably hate him when you grew up. He even likes you a little, deep down. But that doesn't mean he likes being your father.
