Anything but this (pleaseā¦?)
It depends on what youāre going for. Do you want her to be subtly attracted to him? Intensely attracted to him? Or repulsed by him? Intrigued? Suspicious? Indifferent? Confused? Impressed? How she would describe her feelings upon meeting him for the first time really does depend on the context, as well as her personality (and his, unless he hasnāt spoken/done anything to her yet).
