As he sized her up from top to bottom, it was obvious that she certainly could not have come out by herself since she had difficulty moving about. It was also not very likely that she came with a friend.
Do not forget about what he did for a living. With all said and done, he might know Yan Zhiqing better than she knew herself.
She did not know many people when she first arrived at B City, regarding only Lu Weining as her close sister. This was likely due to the fact that Yan Zhiqing was naturally a reserved person. Not only was she was bad at keeping friends, but she was also rather unwilling to make friends with strangers. It was enough as long as she had one friend; she was reluctant to go out and meet more people. Furthermore, with that mouth of hers, she would make people so angry that they would often leave before she could even befriend them. Hence, she only had one friend in the form of Lu Weining for the longest time.
