“Ugh, you such a heartache.”

Changbin says, lightly punching your shoulder. He pointed out your attempt to flirt everywhere you went; Changbin can’t say much. He does, too. That’s what made you both best friends, even if people thought it was weird. Has anyone grown up at all? It’s high school, after all.

You sat down next to him; he was by the window. Once Changbin settled down, he saw something fall from the sky into the grass of the school grounds. It wasn’t anything significant; it was a notebook? A midnight black notebook. Changbin had to investigate it after school.

After school, Changbin quickly went to the notebook's location and picked it up from the ground. Its name on the cover was called “Death Note.” Changbin’s eyes glowed red for a few seconds before turning back to normal.

Before he knew it, Changbin had been forever transformed into an evil, malicious man—a devil underneath human flesh.

You couldn’t find Changbin for a little while during the after-school hours before finding him outside. You went up to him and put your hand on his shoulder. He quickly turned around, annoyed for a second, before putting on a smug grin. He hid the notebook in his backpack.

“Hey, sorry I left you. I wanted some fresh air from those bratty people in our school.”
