The screen flickered. A soft, electric hum filled the room. On the PDF, the two carbon atoms shivered, and the double bond stretched . A lone electron, depicted as a tiny, glowing dot, detached itself and floated across the page, landing neatly on an adjacent hydrogen atom.

That night, he opened the PDF again. The glowing highlights were gone. The text was just a normal, grainy scan of A Textbook of Organic Chemistry by Arun Bahl . He tried to place his hand on the screen. Nothing happened.

"The electron is not merely a particle," the text read. "It is a shy creature. It moves only when you truly believe it will."

The Ghost in the Machine

He looked at the final page of the PDF. A new sentence had been added, typed in a simple, black font.

Every night, he would stare at the complex ring structures of benzene and the endless, tangled webs of reaction mechanisms. He would trace the arrows of electron movement with a shaking finger, but the concepts slipped through his grasp like mercury. His first-year engineering exams were three weeks away, and he was failing.

And that was when the strange thing happened.

Aarav blinked. That wasn't in the real book. He rubbed his eyes and read on. The next paragraph, which should have been a Hückel's rule example, had transformed. It was a set of instructions written in the second person.
