It takes a lot to peak Light Yagami's interest.
He'd been going to his mundane school, learning things he already knew, and if he didn't know them he would within the class period they were assigned. He prides himself on being the top student in his school, hell, he might even be the top student in Japan. He rarely comes across something he doesn't understand.
Mulling over his boredom and the redundancy of the so called teachers who probably weren't as intelligent as his right hand, he glanced out of the window.
He found something he could not seem to comprehend.
First it was the notebook. It had fallen out of thin air, and no one besides himself had seemed to notice it. He almost dismissed it as a trick of the light, or his mind hoping desperately for something interesting to happen.
But then the girl came falling after it.
He will make this clear to anyone who asks, (not that anyone would seeing as they're too oblivious to notice a teenaged girl falling from the sky, let alone a notebook) there were no trees from which she could have fallen. Nor were there any buildings that she could have fallen (or jumped) from. The wind was not strong enough to carry her as far as she was from the nearest elevated area.
Thus, he concluded, she had come with the notebook.
Her appearance should have been impossible. Light assumed she would have at least suffered some broken bones or head trauma from a fall of that height, but she had stood up almost immediately without even stumbling.
Until she had seen the notebook.
(Until she had seen me.)
She seemed frightened of him. As soon as she saw him, she looked like she was ready to faint.
She had started away from the notebook, but then thought twice. She had crouched down near it, never touching it. She had stood a second time and turned toward him. She'd made eye contact.
And then she ran.
Light could only come to one conclusion about this odd occurrence.
(She made eye contact.)
The notebook was for him.
