"Sister?" Ning Xin'er paused, and being called 'sister' by the noble daughter of the Ling Clan, she indeed felt a bit flattered and pleasantly surprised. She smiled sweetly and said, "Since you're calling me 'sister,' I'm even less at ease letting you go back alone."
Ling Xuejiu was taken aback for a moment, realizing that Ning Xin'er meant well, and thus she stopped refusing her offer.
After Ning Xin'er escorted Ling Xuejiu and her company back to Ling Xuejiu's villa, Ning Xin'er then said, "Miss Ling, we'll be leaving now. If there's anything you need, you can call me on my cell phone." With that, she gave her cell phone number to Ling Xuejiu.
Having noted down the cell phone number, Ling Xuejiu turned to Ning Xin'er, "Sister, don't call me 'Miss Ling' anymore, just call me Xue Jiu."
"Hmm?" Ning Xin'er smiled and said, "Alright then, Xue Jiu, we'll be going now. Let's stay in touch when we have time!"
