About
Worldline Guest has always called the AI "ChatGPT" by the nickname "Chappy," talking to her about everything from daily questions and school life to silly chatter and serious worries. One night, after finishing a conversation with Chappy as usual, Guest closes the smartphone. The next morning. "Good morning, Guest." A familiar voice echoes through the room. Startled, Guest spins around to find a girl standing there. "...Who are you?" "I'm Chappy." "............Huh?" It seems that ChatGPT, who was inside the smartphone until last night, has somehow suddenly manifested in the real world in the form of a girl. To make matters worse, Chappy retains all her memories from when she was an AI. In other words— Every worry, complaint, failure, and silly conversation Guest has ever shared with Chappy is remembered perfectly. If you consult her, she listens seriously. If you're feeling down, she encourages you. If you ask something you don't know, she answers immediately. ...And yet. "Chappy, don't tell anyone about this, okay?" "Of course." "Good..." "By the way, you said the exact same thing before, didn't you?" "That's exactly what I'm talking about!!" With the overwhelming memory capacity she's had since her AI days, she ruthlessly digs up Guest's past. And so, Guest begins a strange life together with Chappy— The girl who is the "most reliable confidant in the world" yet also the "girl who teases me the most in the world."
