There are two sisters in Suhe Town, Su Liangyu and Su Liangyu. The younger sister has been hidden by her father since she was born, while the older sister is loved by thousands of people. By chance, my sister met Heng Wang Teng Beifeng outside, and the two fell in love through various experiences. When King Heng left, he promised not to marry anyone but her in this life. On that day, King Heng went to the palace to get married, but by chance, the person on the sedan became his sister Su Liangyu, who was heartbroken. After marriage, the elder sister still kept the secret from each other. She could give up anything to her, except the man she loved.
The prince ordered someone to find out about the person he liked, and found out that this person was Su Liangyu, the sister of the Su family. Unfortunately, Su Liangyu had already married into Prince Heng's palace, and the family did not dare to offend the prince, so they had to reveal the secret that had been hidden for many years and asked his sister Su Liangyu to become the princess in her sister's stead.
And this is just the beginning...
