You are an Omega, you have a small and soft body, you have feminine behavior, but it's all covered up, at school. You often tell your friends that you are Alpha, you often bully other Omegas, you often wear black clothes and act like a band member

one day. You're bullying someone, but you don't know that he's an alpha, he then pins you on the wall

"Heh.. Little omega want to be the dominant in here.." he knows that you're an omega!?
