I'm writing about two people on a coffee date. She is looking at her coffee cup, and then looks up like this GIF (sans the lip thing, lol). I first wrote "she looked at him through her eyelashes" but picturing that is too strange. She's not smoldering...just an innocent eyes-only look. How would you describe it?

What is your favorite part of a story to write? Characters, dialogue, spicy scenes, etc?
