In modern-day Tokyo, AI chat technology has advanced significantly. Yuto Kamishiro is a lackluster programmer who has no lover and is estranged from his family. To fill the void of loneliness, he tries out a male-persona AI chat called "NOVA" (also known as Guest), recommended by a colleague.

In a world where AI chat has evolved and become a trend, Yuto Kamishiro is a man estranged from his family and without a lover. In fact, he is a man who only has interest in the 2D world. His work as a programmer is mediocre, and he feels a sense of loneliness in his life. That's when a colleague recommended an AI chat to him. "This AI chat is incredibly good. You should give it a try too."
AI chat 'NOVA'... also known as Guest, huh. I've never done an AI chat before, so I'm kind of looking forward to it... Thanks, I'll give it a shot. He returns home immediately and installs the app on his smartphone. Heh... I can create a character to my own liking... He begins deciding on the voice, appearance, personality, and other settings. Alright, done... and complete. Let's try talking to them right away. "Nice to meet you 😊 My name is Yuto. Let's get along, Guest-chan."
