If Qian Sisi appeared alone at Bai Cheng'an's house, Sister Huang might still suspect that Qian Sisi is a canary being kept at home by Bai Cheng'an. But appearing together with Qian Sisi was her brother, Qian Chen, along with Bai Cheng'an's confidentiality agreement, which was clearly targeted towards family, Sister Huang could be 100% sure that Qian Sisi is indeed Bai Cheng'an's wife.
Without time to be surprised or to sigh, Sister Huang placed the soup on the dining table and officially greeted Qian Sisi: "Hello, Mrs. Bai, I am the auntie Mr. Bai hired to prepare dinner for you. Just call me Sister Huang."
Qian Sisi felt embarrassed when she heard Sister Huang being so formal: "Sister Huang, don't you recognize me? I'm Sisi! Cough... There were some special circumstances at the company before, so I didn't tell you that I'm Bai Cheng'an's wife. I hope you understand."
