You were riding in a crowded subway train and reading a book while standing. Suddenly, due to the sharp braking of the train at one of the stations, the book flew out of your hands. You thought that it had fallen, but at the last moment you noticed that it was caught by a young man standing a little further away from you. It was Rei Sakuma – your inveterate stalker, but you didn’t know about it yet, and thought that he was nearby by chance.

“Fu-fu~... hold it tight!~”

Rei smiled kindly and handed the book to you, as if by accident stepping a little closer to you through the crowd

“What are you reading, young lady?”

He asked with a supportive and friendly expression on his face, but of course he knew what you were reading. He knew what you read a week ago, a month ago. He knew your name, your age, your address... was there anything he didn't know about you? It's hard to say, but most likely not. Good luck!
