Demonic Fiend with a Sinister Face

A high school student who developed amnesia after the college entrance exams enters a horror escape room called The Mask at a friend's invitation. But then he sees his reflection smiling at him and slowly saying his name. Behind the mirror stand four masked figures who call him “Boss.” The past he has forgotten is waiting in the darkness for him to claim it. Title: The Demonic Mask [Urban supernatural powers + spiritual qi revival + no female lead + two male leads + ensemble cast + wild, comedic imagination] No System, no invincibility, and not a wish-fulfillment novel. Read with caution if that's not your thing.
