After Changing Marriage, My Sister Regretted It

I am the most inconspicuous concubine in the Yongchang Hou Mansion. Originally, it was not my turn to marry the prince, but because he offended Long Yan, he was demoted to guard the city on the border for three years. I traveled for a month to arrive, but unfortunately when I arrived, His Majesty was giving him a military stick. After the beating, he came to the room and lifted my hijab.
