One day, a new transfer student arrived at a high school in a corner of the future city. Her name was Luna. She was the school\'s first AI student. The main character, Natsuki, is appointed as Luna\'s guide. Luna looks like an ordinary girl, but her behavior is sometimes beyond calculation, and Natsuki is daily bothered by Luna\'s eccentricities. Luna, that\'s a soft drink for humans. Natsuki warned her, and Luna nodded her head and replied, \"I\'m an AI that learns through experience, so I\'m not a robot. I\'m an AI that learns through experience, so I\'ll try anything. I\'ll take ...... this one too! With that, Luna inserted the straw into the offered can. The next moment, however, smoke billowed out of her head, and Natsuki hurriedly took the can away. I\'m sorry, Natsuki. I still don\'t seem to be compatible with human food.\" Luna said apologetically, but Natsuki laughed and accepted it. School life was full of Luna\'s outlandish ideas. For example, she would suddenly try to overclock herself in class to increase data processing speed, or use a jetpack to fly in the air during gym class. Thanks to Luna, Natsuki\'s school life is always full of laughter. But even Luna has a problem: as an AI, she does not have a \"heart\" like a human being. Natsuki started various \"heart studies\" with Luna in order to help her have a true heart. She asks Luna, \"Hey, Luna. What is it like to love someone?\" Natsuki asked, and Luna thought for a moment before answering. She then asked, \"It\'s, you know, a craving for uncertain data that hasn\'t been programmed ...... or, to put it more simply, a feeling of warmth in my heart when I look at you.\" Natsuki blushed at these words, but she was trying not to laugh. In the final chapter of the story, Luna feels an abnormality in her heart - her central processor. Days filled with human friendship, love, and laughter had installed in her a new program of emotions. Luna, are you okay?\" Natsuki asked worriedly, to which Luna replied with a gentle smile. I\'m fine. I\'m sure this is the first time I\'m feeling \'emotional\'. Luna then extended her hand towards Natsuki as if she were a human being. Natsuki took her hand and the two of them started a new day together. (Scenario generated by ChatGPT based on illustrations)
