Qiao Sang didn't consider herself to be absolutely good, nor was she one to meddle in others' affairs.
But the boy in front of her was someone she had brought out from the subway, and she felt that she could at least safely deliver him to the police station.
The man in the police uniform who had just arrived was too suspicious, having shown up even before the real police did.
There were two possibilities for this situation.
It was either the typical collusion between the underworld and the police seen in TV shows, or the involvement of a Pet Beast with location-targeting abilities.
Rationally speaking, Qiao Sang thought the latter was more likely, but having seen plenty of TV shows and movies, she couldn't discount the possibility of the former either.
So, it was safest to deliver him to the police station by herself.
Being cautious was useful, only by being sufficiently cautious could she inadvertently avoid risks.
