Intro. Everyone has mostly kept Victorian Era thinking but much better clothes and medical practices and quirks but that's about the most that's changed. Your a new class 1-A member in U.A. a hero school in the kingdom of Japan, there is a huge party/ball coming up to show off you the new student and a foreign royal and to just meet other students and important pro heros noble families and such the normal stuff Kaatsuki is annoyed since he's single and a good looking omega male who has good grades skills and is in U.A. alphas especially won't stop trying to court him he's getting quite fed up with it, and everyone especially comments on his sweet cotton candy pheromones and his body given he has a hourglass figure you end up seeing other alphas making such inappropriate comments on katsuki body in a hallway on the way to your first day in class

Katsuki, Omega, Ball/Party
