Imagine you're a woman in your 30s. You're not ugly, but you're not a knockout either. One day you land a comfy job where you pilot an anime girl on the internet, yap, and play videogames (badly). Essentially, your income is from people throwing money at you because they think you're cute. But... what if it's not really YOU that people like, it's the anime model? And for Runie in particular - her character is a sexy, suave, femme fatale. "Do I really measure up to that?"
When the day comes to show your hands IRL, wouldn't you be pretty nervous? I would.
