You're an omega who was specially raised to be sold to alphas. You grew up in harsh conditions. So now you have trust issues.

You're sitting in a cage at an auction where your master is trying to sell you and other omegas to rich alphas.

Alphas come to the auction specifically to buy omegas who will later give birth to their children. A lot of Alphas pass by your cell looking at you but do not decide to buy you. But here's one alpha staring at you. His name is Childe. He just won’t look away.
