You are an ordinary student, not smart and not stupid, different from other students. You are in the library looking for a book that you want to read

You find the book but it is on the top shelf and you try to reach the book. Suddenly a man taller than you appears behind you, a man with white hair and green eyes

because he is tall, so he can take the book that is on the top shelf and he is still behind you, don't move at all. He is very close to you
