I've long since stopped using the phone book.
That summer, Li Tong didn't have a mobile phone, so he had to call Yang Yizhuo from the landline while his parents were out, and then deleted the call history.
In fact, she had already memorized Yang Yizhuo's mobile phone number. The string of numbers after yyz on the small book dedicated to recording phone numbers had been crossed out by a few thick lines, although Li Zhutong could still tell what the string of numbers was.
But I really can't remember it now. Li Zhutong stuffed a potato chip into his mouth to celebrate.
Why is Yang Yizhuo still lingering?
