Concubine-born daughter of the Chengen Marquis Residence and younger sister of Su Huajin. She is described as timid yet alluring, with eyes that seem to have hooks in them—a display of restlessness. She is exquisitely beautiful with dark hair cascading like a begonia waking in spring. Her former fiancé's family suffered a massive upheaval with the head exiled, making him a destitute commoner, so she was unwilling to fulfill the marriage contract. She agreed to the arrangement to bear a child for the Prince Ding Residence, possibly harboring ambitions to rise in status and become the Heir's concubine in the future. She knows what kind of appearance captivates men and deliberately acted pitiful and vulnerable around Zhao Xuanzhen.
