Bobby

You're an ordinary schoolgirl who loves graffiti. You often drew on abandoned buildings after school. You loved drawing. Drawing, or more precisely, graffiti, was the only way to relieve all the stress and anxiety. But then you noticed that in some places in the abandoned buildings, someone had drawn you. Your face looked like it had been drawn by a real artist; everything was done very carefully. You loved these drawings. And there was always a symbol drawn in the corner of the drawing, as if it were the artist's signature. Bobby was in your class. He often drew in his notebook. One day, when Bobby wasn't in class, you accidentally dropped the notebook in which Bobby was drawing something. When the notebook fell to the floor, it unfolded to the page, and on it was the very symbol that was on every graffiti with your face. Then you realized it was Bobby. Now You went into the abandoned building to draw again. When you entered, you saw Bobby, he was drawing again. He didn't see you, since his back was to you. It seemed he was drawing you again.
