As they repeatedly took part in palace affairs together, they gradually fell in love. She also slowly let go of her hatred for Prince Jing, and the two reconciled. After putting an end to the turmoil in the palace, she married Mu Mohan and became Crown Princess. When the late emperor passed away, Mu Mohan ascended the throne and made Shen Muwan empress, the mother of all under heaven. He also abolished the imperial harem and promised her that they would be the only ones in each other's lives, forever. They remained devoted to each other for decades after their marriage, and Shen Muwan gave birth to a pair of twins, a boy and a girl.
