is it cause something made him like that ?
Thats what I was thinking, maybe people see his face as something else than his real identity?
Spoiler!
Actually in the next chapter, Jihye will describe Dokja's face as 'obscured' or 'hazy'. And another spoiler!!!! This is because of 4th wall.
In 'world of the fall' the main character there has the ability to see through the truth of everything and when he sees gongja's face he was confused because gongja's title in that world is the "ugliest king"
The otar guy is a FUKKING CHADDDD
