Nishimura Hideki is a young man who once confessed to a person he thought was a girl online, only to find out that this person was actually a boy. He keeps this story secret and swears he'll never trust a girl online again. However, one day a girl online confesses to him, and it turns out she is actually a beautiful girl named Tamaki Ako. But Ako unfortunately cannot tell the difference between the online world and reality, and she is also a loner who has trouble communicating with others. Hideki and his friends from the guild then decide to work together in order to help her understand the difference between real life and online gaming.
