Unlike yesterday, though, she was not alone.

A black-haired girl and a tall boy about her age were playing with her. Another girl was sitting on the bleachers reading a book.

So there I was, standing next to the tribune, in front of the high fence that surrounded the whole court. My hands were buried deep in my jacket pockets as I tried to look unconcerned, like a curious passer-by.

In fact I was nothing more than that: a music student on his way to his shared flat, interested in a basketball game between a couple of teenagers. Still, I felt like a stalker.

Even though the three of them hadn't noticed me yet, I was afraid that if I started moving, they would. And I certainly didn't want that to happen.

But why?
