"Hey, sis, what are you doing??" Tang Nan's voice was breathless from the other end of the phone.
"At work." Tang Yuran poked at the glass window in front of her with one hand while holding her phone with the other and asked in a low voice, "What do you need??"
"Can you actually ask me why I'm looking for you??" Tang Nan said somewhat speechlessly to Tang Yuran, "Have you forgotten what day it is today??"
"Huh?" Tang Yuran froze for a second, held her phone up to her face, glanced at the date, then quickly put on an apologetic smile and said, "Heh, I really forgot."
"Do you even have a conscience?? Forgetting your own brother's birthday!" Tang Nan immediately started berating her loudly, "I don't care, you have to treat me to a big meal tonight!!"
"Got it, got it, I'll come find you after work, okay?" Tang Yuran couldn't help but roll her eyes.
