I Can Only Be a Concubine When Marrying the Prince, but Bai Yueguang Is My Wife? Then I'll Marry His Nemesis

The prince announced that his Bai Yueguang was his wife, and I could only show off to my concubine. Do you want my family to send troops to fight? Don't go! Want my family to help pave the way for him? No way! Then the prince was demoted. He cried and knelt in front of the palace, begging me to marry him and help him make a comeback. I turned around, married his nemesis, and prospered all the way.
