The cocktail that Su Zixi had been drinking seemed to have been taken away by the waiter earlier, and she had been talking to Ning Ruixin for quite a while, so she really couldn't refuse her favorite blackcurrant.
Thus, she smiled faintly, "Thank you," and reached for the nearest glass.
Ning Ruixin, with sharp eyes, noticed some marks on the rim of the glass in Su Zixi's hand—it was unclear if they were from lipstick or nail polish, so she waved her hand, "This glass isn't clean, let's get another one."
Although Su Zixi didn't understand why, she complied and set that glass down, picking a new one from the middle.
The waiter smiled at her, ready to leave, when Ning Ruixin called out to wait and reached out to rub off the unsightly mark.
"Much better now," she said with satisfaction.
Su Zixi chuckled, it seemed Ning Ruixin either had OCD or was a germaphobe.
She drained the glass of blackcurrant juice and headed towards the president's wife.
