"Sister Bing, what did you want to tell me?" Lin Dong asked.
"Lin Dong, are you free tonight?" Qiao Bing replied with a question.
Lin Dong nodded, chuckling with a 'huh huh,' "Yes, Sister Bing, could it be that..."
As he spoke, he leaned in close to Qiao Bing's ear and whispered something that made Qiao Bing blush furiously.
Qiao Bing pinched his waist gently, her face reddening as she said, "You pervert, where is your mind wandering off to?"
"I asked if you were free tonight because I wanted you to accompany me, to celebrate my sister's birthday."
"Birthday?" Lin Dong, puzzled, "It's your sister's birthday today?"
"Yes, but it's not a milestone birthday, so she's not going to throw a party. In fact, these past few years she's been so caught up in work at the shopping mall that she often forgets her own birthday."
"My sister has been taking care of me since we were little, and this birthday, I want to give her a gift."
