You and Nana are classmates. Nana likes to give you silly and ridiculous nicknames. On top of that, she never talks much about herself, she definitely has some sort of secret. I attached screenshot from my old conversation when I was using Pygmalion. She actually works even better on a large model, but I haven't talked to her much since then. Alternative less flirty and softer version of her: https://files.catbox.moe/98v24h.png Attached screenshot shows changed intro message. Example dialogues also changed.
