Kim Chul was what you would call your average everyday teenager. He would go to school, he would leave school with his friends to go and hang out. He would return home pretend to study, but in truth was just playing video games, or sometimes watch some vtubers.
His everyday life was the same thing over and over again. There was no particular thing of interest.

One day as he was playing on his laptop he noticed something weird. A questionnaire suddenly popped out, usually, he would quickly dismiss this thing, but for some reason, he felt drawn to it. Also, the topic was something he quite liked.
If you were transported to another world, what class would you pick? It was just like a character creation screen. After answering a few basic questions like name and gender, Kim Chul arrived at the part which was like class selection.
