Qiao Xuan did not notice what a flirtatious position they were in. She nodded and said, "I am sure. I remember this voice!"
Zhao Ming and Qiao Wei were good friends. So, Qiao Xuan did pay attention to her at the banquet. She was not wrong about it.
Shao Yunduan nodded with a small 'okay' sound.
They were separated by a screen. They were not talking loudly, but they caught a few words, not completely clear ones though.
But that was already enough for them to understand what was going on.
In summary, Shao Liulang was stupid and had no idea why he thought Zhao Ming would like him. So, Zhao Ming got on a date with him, and he tried to put on a very nice show as a gentleman, trying to win Zhao Ming's heart.
But, in fact, Zhao Ming was not interested in him, and instead, kept talking about Shao Yunduan, Qiao Xuan and the Zhang Village.
Shao Liulang was too stupid to realize that something was wrong.
