Liu Xinyu said bye to Yi Qin and then wore the new sneakers on her feet too. Looking at them, she was reminded of how Nan Xing looked at her that night. She had noticed the strangeness in her eyes when she looked at her shoes. She didn't understand it at that time but she was able to understand everything now.
Nan Xing was with Yi Qin when the latter bought those shoes and there was even a high chance that she paid for the shoes too. That's why she looked weird when she saw her wearing the same style of shoes. If you run into two people who bought the same shoes from the same store on the same day but at different times, you'd obviously pay attention to it, no? Especially if you know both the people in question.
Liu Xinyu checked if she was missing anything and locked the door to leave. Passing by Qi Yuze's door, she stopped again.
"You keep stopping here," reminded Yiyi.
"He hasn't returned," answered Liu Xinyu. "Or did he leave early again?"
