Huang Shuyi was shaken once he heard how Xiang Wai addressed Raelle. And when Raelle didn't seem to mind the way Xiang Wai called her, little sister. He was suspicious before staring at both Raelle and Xiang Wai with a scrutinizing gaze. However, he couldn't really find anything at all. These two had nothing in common.
Oh, wait!
He suddenly realized that these two indeed had something in common and that seemed to be their surname. Xiang. He mentally facepalmed himself and gazed at Raelle curiously. It wasn't that he didn't know that Xiang Wai had a younger sister. He actually knew this fact. As for anything else about this younger sister? It was completely blank.
The only thing he seemed to know about Xiang Wai's sister was what he heard earlier from her that her sister was a genius. His lips twitched as he mentally screamed, 'Genius? That's right! That's a prodigy right there!'
