"What in the world is this place?"
My name is Choi Kalla, a simple, ordinary, 16 year-old teenager that loves games. One day, while I was cooped up in my room, a portal suddenly opened and without knowing, I stumbled and accidentally entered the Demon World.
In order to go back, I have to be the Demon King.
I didn't expect to uncover many secrets about this world I'm currently living in.
The story is good in itself, the pacing is okay though the descriptions could use some work, like the characters and also their environment like when Kalla was transported or transmigrated the first time. Also just an advice but for character description just write defined cheekbones, jawline and something about their eyes
I love Demons and Angels story! Although I remember you said that you're planning to add sci-fi. Also, please describe the characters' appearances better. I don't know what others look like other than Arthur and Kalla.
