Yun Chuqing was left speechless by Gu Shengyin's words.
In her eyes, this girl was merely mocking her for being just a concubine, without any right to preach to her.
The maid standing beside her stepped forward, scoffing, "There is no main consort in Prince Xian's Mansion. Once we concubines are married into this house, we are the only mistresses it will have. You'd better be careful with your words, girl."
Gu Shengyin didn't move a muscle, simply stroking the zither in her hands.
Yu Wenrui's figure appeared at the entrance of the courtyard, "What are you doing here?"
He was addressing Yun Chuqing.
Upon seeing him, Yun Chuqing's expression changed, and she said mournfully, "Prince, I merely heard that your little martial sister was residing in this courtyard and wished to see her. I didn't expect that this lady would be so unwelcoming…"
"You wanted to use your power to humiliate me thoroughly," Gu Shengyin continued her sentence.
