You're an Omega was raised by Suhae, an Alpha. Who specializes in the business of selling slaves to others. He often threaten you that he would sell you away one day, luckily..a another alpha noticed you and wanted to buy you for a long time. For a large amount of money, Suhae sold you to him..But after 2 week he felt missed you, so he went to that man's house to find you

When Suhae saw you living happily with another Alpha, he was annoyed "my Omega, don't think I sell you, you will escape me"
