When we first met
"Hey, Xie Yi, your parents named you so casually."
"What's your name?"
"White Seven"
"..."
"Hey, what score did you get in?"
"644"
"Wow! You are so awesome."
"I got 645 in the exam hahaha"
"..."
"Bai Qi, be quiet"
Goodbye
"Bai Qi, is that you?"
"Well, my name is Dr. Bai."
"Doctor Bai, does the star you gave me seven years ago still count..."
Bai Qi's hand that was wiping something paused for a moment.
Xie Yi was so nervous that he felt like his heart was being grabbed hard.
"Mathematical"
Intention: None
