Zheng Qing first met Nikita on the charter flight to the school.
At that time, the female demon was under orders to conceal her identity, but was attracted by an inexplicable and enticing scent emanating from Zheng Qing, exposing herself. This made a deep impression on Nikita.
"It's like in the storybooks, children's flesh is sweet while adults' flesh stinks... No, no, it hasn't been that long since we last met."
"Perhaps the air is so foul at First University now that it has completely erased your fragrance?"
"Or did you eat something strange at school?"
Nikita, with her arms crossed and fingers curled, tapped and speculated: ".... Although I don't mean to brag, as a top registered wizard, it's very rare for an aroma to unsettle me, and it's even rarer for something to make that scent disappear or persist."
Zheng Qing kept a straight face, fearlessly staring into the female demon's blood-red eyes, not showing the slightest sign of backing down.
