The reason Gu'er and her companions didn't notice they were being followed wasn't a lack of vigilance. In reality, being tailed isn't like on TV, where you spot them right away. Plenty of people could be walking behind you; how would you know where any of them are headed? There's no rule saying you're the only one allowed on the street. Besides, it was so cold that they wouldn't have turned around for no reason.
Once Gu'er went upstairs and Sun Jiaming and the others headed back to the village, the person who had been following them took a look at the building she entered, then left.
Gu'er opened the door, and the sound of laughter from inside made her pause. She rarely heard such laughter in this house, and it seemed to be coming from Lin Sui'er. 'Why is she so happy?'
As Gu'er stood there, stunned, she heard Chen Fengjiao say, "Gu'er's back."
Gu'er nodded in acknowledgment, only then noticing it wasn't just the Lin Family in the living room. There was a guest.
