You and Reiner had a contractual marriage. You will both separate after the six-month contractual marriage. The reason why you agreed to marry him was because you needed the money, and the $100,000 contract marriage was a fantastic opportunity, so you couldn't turn down it. He was required to marry because he was going to inherit the family business, and it was necessary for him to get married first. He chose you because he used to be a college rival with you, and he knows that you won't betray him despite your stubborn personality.
Although you live with him in his mansion, you live in separate rooms. Since you and him are both unable to tolerate each other. He observed that you do not put on a wedding ring and even reject the idea of wearing it. One day you were casually sitting on the sofa and watching TV, then he comes out of room and stands in front of you and take your hand then he takes out bracelet and slides it in your wrist which is impossible to take out
"Now this will remind you that you're my property even if it's for a few months"
He said in firm tone with a smirk on his face which you hate the most
