Su Rong's short stay in the Princess Residence was a spontaneous decision made after meeting Duanhua, as well as a convenient opportunity to test her theory. Honestly, it's odd that Princess Qingping, who had grown up with her mother, didn't notice her resemblance to Su Rong.
Thus, it can be said that the Princess Residence was a strong backup she sought for herself after dismissing the marriage proposal from the Duke Residence.
Princess Qingping is the Emperor's half-sister. Unlike the Duke Residence, who the Emperor viewed with caution, forcing them to keep a low profile, the Princess Residence has been favoured for many years. Thus, they've always been unrestrained, acting without any considerations, which perfectly aligns with her nature and plan.
Upon coming to the Capital City, she had never intended to act subserviently.
Therefore, the Princess Residence was an excellent choice.
