Why did this kid notice me?

"Much better. Xinxin really made the right choice to study medicine with grandma Xiao. With her talent, she's probably the child of those clans who have been dreaming of having medical skills for generations." Cheng huaijin said with a smile.

"Of course. Xinxin is much better than my grandson, who has been by her side since she was a child. She has learned more in four years than I have in fourteen years." Lu Zheng said proudly.

He could tell that there was something different about Gu Xin, but he couldn't let anyone else see it.

In fact, when the ten thousand swords sect threatened him with Gu Xin during the Lantern Festival and he stabbed himself, he had already guessed that Gu Xin had something good on her.

He was even more certain when he recalled the time when he returned to Yuzhou and the sweet food that Gu Xin gave him.

It was just that he never said it, and never asked.
