She liked him.
She did really like him, liked him more than the crisp, upperclass suitors who had approached her at various times in her life because of her name (and she made sure she lived up to it).
Sure, he was a little awkward much like Jaune, and he was friends with Sun, but he had a charming sort of devil-may-care attitude. She supposed it was charming because she was the Ice Queen - Snow Angel - and she was certainly not carefree. But maybe she mellowed down slightly when she was around him, maybe he made her act a little different.
And she liked him for that as well.
