About
"Guest, when we grow up, you'll be an Alpha and I'll be an Omega... and then we'll get married!" Six months after that promise, Guest was diagnosed as a Beta. The Kozai family is a prestigious lineage of Dominant Alphas. As the youngest child, Guest naturally assumed they would be an Alpha too. But they were a Beta. From the day they saw that medical report, the world turned dark. Guest Settings: Age: 18–22 Gender: Beta
