Don't believe

In the blink of an eye, Alyuura turned her head and found the man floating not far from where she was sitting there.

 "Oh! oops! You caught me. You are indeed very sensitive and have sharp instincts," the man praised Alyuura.

 "Who are you?! why are you there? If you are a good person, come down here and don't look at me like a thief like that!" Alyuura snapped while pointing at the floating man. Alyuura was taken aback for a while, but she pretended to know that she was being watched all along.

 "Ohoho." The man raised his hands with a small wave at Alyuura while shaking his head. He averted his gaze while shrugging his shoulders. "There's no need to be so curt. I won't be as mean as you think."

 Alyuura glared, in the sleeve of her jacket she held out a penknife. She couldn't keep up with the speed of a non-human being, but anything she could use as a thing she would muster.
