Assumptions

Xavier came out of the room he is residing. The first sight that caught his eye is the Auburn-eyed stranger feeding the pretty female. 

His mood instantly plummeted with the sight but he didn't know why it even bothered him. The stranger is her mate and Xavier didn't have any right to feel like this. But it seemed that his heart had other thoughts. 

Another thing that Xavier found hard to comprehend is the harmony in this family. All of her mates were formidable except that silver wolf and Lion. No, formidable is not the right word. Each one of them except those two is an immortal beastman. 

Not everyone can cross that level. But seeing multiple of them in a single place felt bizarre. Staying in this place he learned a few things about their family. The current Eagle and vulture king that he didn't yet meet are also immortal beastmen and they too were this pretty female's mates.
