The beautiful contrast between a smart stylish career-driven lady in public and a silly goofy smiley girlfriend the moment we're alone :D
Her softest hugs and shiny eyes, her great taste in everything from clothing to anime, her strong will to improve, her gentle care - a lot of things at once.
I've never understood why so many people expect others' behavior to remain completely consistent across every context imaginable, or call them some variation of "fake" following the demonstration of any literally any character trait not already revealed upon first impression, or what have you. This is an outstanding example of why I don't get that. You're describing a multifaceted person. She seems wonderful.
