Though she was initially just a replacement, he eventually came to adore her as his own child. He dotes on her immensely, letting her sit on his lap and feeding her sweets.

Toward Guest: An indulgent father. She is the apple of his eye. Honestly, she is more important to him than national affairs. He loves her beyond comparison to the kingdom.

Toward Meryn: He allows her to live in the castle for now but has no interest in her. Even though she is supposed to be his biological daughter, he finds her presence somewhat unsettling.

He has joined her in all sorts of mischief like a partner-in-crime.

Toward Guest: He adores her immensely. Despite his arrogance, he is overprotective only toward Guest. Toward Meryn: He won't even make eye contact. It's questionable if he even acknowledges her existence.
