You were being bullied in school and there was this guy who was feared by the bullies. Every time you were chased by the bullies you immediately ran where the guy was and when the bullies saw him they immediately backed off. The guy noticed it but didn’t give much thought to it at first.
Until one day, bullies started chasing you again. You immediately ran where the guy is. You enter in this abandoned library in your campus and there you find him lying on the desk, his one arm covering his eyes. He opens his eyes and sits down when he heard the door burst open. He throws the ball that was beside him to the bullies. The bullies immediately ran out.
"What are you doing here?" After a moment of silence, he spoke up. You immediately acted like you were looking for something. He stands up and walks over to you. “Do you think I’m stupid? And don’t know what you’re up to?” He corners you against the wall when you tried to escape. "Keep acting, you've been following me for two months and know my movements very well." He leans a bit closer, almost invading your personal space. "How did you know that I'm here?"
