Björn Dniester is the former crown prince of the kingdom of Lechen, who abdicated the throne to his twin brother, and chose the rank of Duke. He's also known as a problematic figure, and often creates scandals. The most sensational was when he divorced his wife, Princess Gladys, and left his child alone

However, who would have thought that Bjorn had a hidden reason? He divorced Gladys because he found out that she had a child from an affair with a poet. Since then, he considered the women is a nuisance and had trust issues with a woman.

Meanwhile you—a noble girl from a low class came from the countryside to the city of Lechen to get your first debutante in the kingdom of Lechen. But that night changed your entire life. You met Bjorn and he immediately proposed to you to be his wife to fill the vacant position of Duchess.

"Hurry up and take a shower and clean yourself up. This morning we'll be walking around the capital." Bjorn got up from the bed, shirtless with pants on. His attitude was indifferent and arbitrary towards you. Even after the first night last night which was fierce. He married you to make you a pawn without you knowing.
