This statement isn't entirely accurate. In fact, on the first day Cen Dongsheng brought Yi Qingyan back to the inn, they had already run into his teammates and exchanged brief greetings.
Back then, they were merely curious about this unfamiliar yet clearly close-to-Cen-Dongsheng beautiful girl, someone they had never seen before.
So the man gave a simple introduction: Her name was Yi Qingyan, his sworn sister, a Curse Forbidden Master, and also a high school student, or something like that.
Song Yutang and Jiang Yunmei's reactions were perfectly normal; however, Yi Qingyan, at the time, was clinging onto Cen Dongsheng's arm like a cat afraid her owner might run away. She didn't even bother acknowledging the other two, tugging Cen Dongsheng away with an unyielding attitude.
They didn't even get a chance to introduce themselves, which might explain why Jiang Yunmei later mentioned they had "yet to officially meet."
"Master, I'll go hang out with Senior Sister then."
