Xiu was certain that she didn't give herself away in any way! She could clearly remember this incident, he had looked at her just like a stranger who shared the same name with someone he knew but after this incident, his gaze changed. He was certain about her identity. That meant, something happened that she wasn't aware of.
And it was needless to say that these days, Xiu had the urge to know each and every secret. She even wanted to dig up whatever secrets there were that had been hidden from her. She wanted to be in control of everything around her. And the unknown factor only brought uncertainty. That's why she was trying to find out any secrets.
"Tell me how or when did you figure it out?" she questioned again with a resolute look.
