Over the weekend, Ren Chuqing was going to return the sachet to Professor He. She had already called Professor He, and even obtained his home address.
However, just when she was about to leave, Wen Muqing also wanted to go out with her.
"You're going too?" Ren Chuqing was taken aback.
"Since I don't have anything else to do at home, I might as well go with Sister," Wen Muqing said.
Ren Chuqing glanced at her companion and thought that since it was just a matter of handing over a sachet to Professor He, she agreed.
They drove to Professor He's residence, an old neighborhood, but the environment was quite decent.
Following the address, they arrived at Professor He's doorstep. Ren Chuqing rang the doorbell, but no one opened the door.
Ren Chuqing was puzzled, so she called Professor He's mobile phone. Immediately, she heard Professor He's voice over the phone, "Is... is that you, Chuqing?"
