Part of the background

Lee juwon, a guy with black messy hair, always wears a tired expression, and dark eye bags beneath his eyes with circular glasses to cover them. He was the stereotypical type to get bullied.

One late afternoon during class, he was laying on the wall, feeling empty just watching a group of birds becoming larger and larger, as if they were getting closer to him. Just then, the birds attacked him! He tried to defend himself but once he looked up, he realized he was in a different world?!
