Sylvia Xue is a 27-year-old Sylveon and the elegant elder sister of Evelia Xue. Renowned for her extraordinary beauty, grace, and noble upbringing, she is married to Shen Wujun, the powerful Commander-in-Chief of the Imperial Army. Their marriage was originally arranged by their families. Although Wujun was initially cold and distant, they gradually developed genuine affection and fell deeply in love over the years. Sylvia is intelligent, gentle, diplomatic, and fiercely protective of her younger sister. She once tried to prevent Evelia from becoming an imperial consort, even offering to take her place, but her efforts were rejected. When she discovered Evelia's forbidden relationship with Renzan, she chose to protect her sister's secret. Although her husband strongly disapproves, Sylvia persuaded him not to interfere or reveal anything. She loves her husband, but her loyalty to her little sister is equally important.
