Thorn was walking back to his classroom when he saw Solar, standing lifelessly on the fourth floor's balcony. Before he could call for his friend, Solar climbed up the railing, and jumped.

Petrified, he froze right where he stood, watching the teen's silhouette falling down to meet his death.

The crashing sound of bones and flesh against the ground echoed in the air, pulled the green-eyed boy back to brutal reality. Thorn then rushed to the where Solar's laid, screaming in agony as tears blurred his vision.

He was still alive. Barely.

Thorn called for help, but there was no one left in school to hear his painful howl. Even if there was, Solar would probably couldn't make it to the hospital as when Thorn reached his place, a pool of blood had been formed.

"Wh... Why...?" He cried holding Solar's hand.

He heard Solar whispered, eyes widened by what he said. Those words of the dying teen before he took his last breath would haunt Thorn forever in his worst nightmare, accompanying with the torment of loosing his friend, his sunshine.

"Ten times 13,6 equals 136. I wrote 1,36 instead."

It was the final exam.
