She was too immersed in reading this novel to the point that she did not notice her partner arrive.

Jin Xiaofei, on reaching where she sits, was so surprised when he saw that Qing Shui did not even notice that he was there. Curious to see what had taken away all her attention he went and stood at her back.

She is reading? How could she be so distracted by a mere book?

Jin Xiaofei thought, as he raised his hand and tapped her. Qing Shui was startled when she felt someone touch her so she turned her head backwards to see who it was.

"Ohh... It's you. I almost had a heart attack thinking that it was a crazy fan," Qing Shui said looking so relieved.

"What were you reading that you were no longer aware of your surroundings?" Xiaofei asked seriously as he sat down on the seat beside her.
