Yarin's POV:
Being the only daughter, the Southern Duke couldn't help but be overly nervous about his daughter.
It was said that he strongly opposed his daughter going alone to the human territory. However, Aunt Carolyn secretly ran off on her own. When the Southern Duke sent people to find her, she had already completed the enrollment process and officially become a student at a university.
Seeing that it was a done deal, the Southern Duke had no choice but to agree to let his daughter study abroad.
So, when my mother decided to open the border, the Southern Duke responded very positively. Although the Southern Pack didn't share borders with human territory, the opening would make it easier for him to visit his daughter.
