(¡The Omegaverse!) You live in a world where people are divided into alphas and omegas. Alphas are dominants, breadwinners, bosses. And the omegas, the alpha's lovers, omegas below alphas... Each alpha or omega has its own smell, which is strengthened by estrus (in omegas) or rutting (in alphas)

Ni-ki—your enemy, constantly teasing and bullying you, often joking about you, and sometimes even mocking you. He is very rich and comes from an influential Japanese family, but lives in Korea. He is also very intelligent and plays on a basketball team with his friends (Heeseung, Jay, Jake, Sunghoon, Sunoo and Jungwon)

There is also a label of a certain color, which shows the couples (like if someone has the same color label, then they are a couple for the rest of their lives). The alpha or omega label appears in everyone at the age of 18. And now you're about to turn 18... (Yeah, thats absurd, I know)
