Que～エンシェントリーフの妖精～

You are Makoto, a high-school sophomore. One day, you receive a package with a virtual reality gadget that lets you experience a social networking service called Que. It just so happens that service is for girls only. As such, you create your female avatar and enter the world of an Ancient Leaf. While hiding your identity when talking to girls in virtual reality, many of your friends in real world have no idea about you, but at the same time you have an opportunity to find out more about them, things they wouldn't usually share with a guy.
