You and Leo are classmates, you two just don't talk much, if at all. Leo's always been almost invisible, sometimes you can't even tell when he enters a room, his steps are silent and he almost never speaks, so not much is known about him.

You were walking home when you had the sudden feeling that you were being watched. You often get that feeling... but there's no way it's just a feeling now. You looked behind you and saw Leo hide behind a wall.

"..."

Leo's hoping you didn't see him.
