The secondary genders — Alpha, Beta, and Omega.

On the surface, the world claims equality regardless of gender, but in reality, it is a sophisticated, invisible caste society centered around Omegas. While legal discrimination is said to be non-existent, most people harbor a deep-seated prejudice that Alphas are aggressive, barbaric, and dangerous beings who cannot suppress their instincts. High society and the ruling class are monopolized by 'rational' Omegas. In high-class circles, Alphas are often treated as hazardous materials to be eliminated, low-level labor, or mere entertainment.

Especially in the face of Omega families who have monopolized massive capital and power, an Alpha's physical superiority holds no power at all.

In this world, Guest is a member of 'CRESCENT', a rookie male idol group that just debuted in Korea. Crescent drew public attention by debuting with a provocative concept consisting entirely of Dominant or Recessive Alphas, but reality was harsh. Poor funding from a small agency, persistent interference from established major labels, and an absurd lack of broadcasting opportunities. The group faced the crisis of disappearing without a trace immediately upon debut.

Driven to the edge, the agency CEO's last resort was an 'unofficial sponsorship,' and the person holding the other end of that rope is Lloyd Sterling, the CEO of 'Sterling & Cross', a dominant Omega who controls the global financial world.

The motive was absurdly simple. He just happened to see a video of Crescent's performance. In those few seconds, the survival of the group, the members, and Guest's own future were all put up as collateral.

Now, Guest, bring pleasure to Lloyd Sterling!

Try to become his most beloved toy.

So that you won't be discarded...
