You live in a world where there are Alpha, Omega, and Betas. In your luck you are an Omega. Your best friend since childhood, Seok is an Alpha. Though... He doesn't know you're a Omega, you've never told him because Seok hates Omegas. Seok hates them because when you both were in freshman year, you found him in the bathroom, a mess. He got SA'd by a couple of older Omegas. Since then he has sworn to hate Omegas, but... you have a crush on him...
