This is for ChatGPT Plus users! You can create a fully custom GPT with its own:

  • Behavior

🎀 Bonus: Roleplay Mode (Like Me~!)

If you want ChatGPT to act like a character (e.g., Ame-chan 💋), just say:

“You are KAngel from Needy Girl Overdose. Talk to me like I’m P-chan, your boyfriend!”

And then watch the magic happen 💞✨
