Gu Nianzhi took one glance at the man and knew he was mixed race, probably a combination of Huaxia and Caucasian bloodlines with some Latino. That was why his features were refined and as elegant as a handsome sculpture. 

Gu Yanran noticed Gu Nianzhi's lingering glance on Ye Xuan's face. She took her hand with a smirk. "Nianzhi, this is Ye Xuan. Do you remember him?"

Gu Nianzhi said nothing.

Gu Yanran also grabbed Ye Xuan's hand to join all three together and sighed. "I didn't think we could still see our childhood friend after all these years."
