Zheng Tan felt he had been under surveillance for the past couple of days.
He was uncertain of who was watching him, but the feeling was intense.
Following Mr. Jiao's advice, to avoid that person surnamed Ren, Zheng Tan had recently stayed away from the Life Science Building area; furthermore, he seldom left the courtyard at night, venturing out only during the day when he couldn't bear it any longer.
Usually, he went to the entrance of the Affiliated Primary School around five in the afternoon to wait for the two kids, then they would head home together. Even if he went out at night, he just strolled within the courtyard and never went beyond it, let alone to the alleys of the Old Building District.
During the day, the campus was bustling with people since it wasn't a closed school, and the checks at the school gates were not very strict. However, without determining the source of his feeling of being watched, Zheng Tan couldn't relax.
