Yin Xun felt that there was something wrong with that person's posture. She gave Liu Ying a look, indicating that there was something wrong with that person.
Liu Ying instantly understood and nodded.
Then, Yin Xun said, "I'm going to the washroom."
On the way to the washroom, Yin Xun glanced at the person. She was panicking and looked like she was putting something in her pocket. Yin Xun immediately understood what was going on. She sneered and ignored her.
After returning from the washroom, Yin Xun sent a message to Liu Ying and told her about the person beside her. Then, Yin Xun stood up and said, "Since we've already discussed things, we can't go back on our word now. I'll leave first. Eat slowly."
Before leaving, Yin Xun left some money for Liu Ying.
After Yin Xun walked out of the coffee shop, the thickly-dressed person came to Liu Ying's side.
