Cheng Xiao saw that these two men actually ignored her when she brought up the topic. Instead, they were asking Cheng Ling. This made her feel a little awkward and at a loss.
She continued the topic, "Yes, Sister is older than me by a month, so Sister's 18th birthday is before mine."
Cheng Xiao always liked to speak to them in a soft voice.
She felt that men should like delicate girls with such a soft voice. However, this sounded ear-piercing to Lu Qi, as It was not natural at all.
He looked at Cheng Xiao and said, "Miss Cheng, you always call Cheng Ling Sister. I wonder if you know when her birthday is?"
This really stumped Cheng Xiao. Who cared what day Cheng Ling's birthday was?
But if she couldn't answer, then wouldn't the sisterhood that she had painstakingly fabricated in front of the two of them be destroyed?
She pretended to think for a moment and then said a date.
