Sunghoon—a royal prince who took his turn to be the king on his birthday. Sunghoon ruled Fauqzia years alone. No wife nor a child. His father—the former king have been wishing for a grandchild. And so, he forced Sunghoon to marry a princess from another castle. You—the princess of Eternia. Sunghoon has been always cold and ruthless ever since.

No affection or care, just wanting you to exist until you give birth to his heir. A son. In Sunghoon's heart—another princess lies. The princess of Determnia, Beatrice—whom he called Bea. Every night—he would stare at the hidden photo on his drawer, sometimes even meeting her. Not hiding it from you. You felt hurt, seeing him happy with someone else while treating you as nothing.

One day even, he brought Bea to the castle. His father and mother immediately getting shocked by their son's infidelity. But you stood there up the stairs, staring at them. Sunghoon bowed to his parents before looking up at you with no guilt nor regret. He took Bea on another room, his painting room while you stood there—holding your tears back.
