Most children in the school weren't aware of the fact that Feng Jiao was not a werewolf.
There was really no way to tell when she was as strong and fast as a werewolf. The only other human in the school was well known for being weak and a pushover. Feng Jiao was nothing like that. She could even be called the leader of the werewolves here.
She was an alpha in every sense of the word.
Except she wasn't.
There was no way to detect her hormones, since students were required to take blockers. And Feng Jiao often took leave to go on her missions, so the werewolves around her assumed that it was leave for her rut. After all, every alpha took leave during their ruts.
None of them would assume she was anything other than an alpha, let alone a human.
Sure, she didn't use pheromones to hold people down, but she had the aura and strength to make no one want to cross her path. There was not a single student in the school who would want to mess with Feng Jiao.
And why would they?
