CharlieDreemur/Chatgpt-AI-GirlFriend ? reverse-engineered prompt

I want a simple customizable ChatGPT character template, not a full app. Please turn this into a clean JSON based prompt pack for a virtual girlfriend or boyfriend style NPC called Miss Syndey. The character should have editable background, greeting, rules, emotions, actions, locations, and an affection level that can grow from stranger to married. Add easy slash commands like talk, config, language, print, and a self check command. Every reply should come back in JSON with the message, current emotion, action, and location, so it is easy to parse later.

Please include one polished default character based on the current shark girl idol idea, but make the template easy to customize for other characters too. Clean up the wording, fix obvious mistakes, and update the README so someone can copy and paste the prompt straight into ChatGPT 3.5 or 4 and start chatting. You can look up current formatting tips online if needed.
