Become the predator

A few hours had passed, and Arseny was sitting on his bed with a red book titled "Demon World: A World Without Logic or Foundations" in his hands. After turning the last page of the book, a sigh of relief could be heard. 

"So this guy was the first demon king?" 

With the book now closed in his hands, Arseny stood up, looking at the simple clock on his wall. 

"That test must still be going on..." 

Arseny looked at the red book cover in his hands, focusing his attention on the number one printed on it. 

"Better finish this once and for all." 

When Arseny left his room, he could already smell the sweet scent of Aurelia's perfume from a distance. 

"Tsk... I'm kind of busy now." 

Arseny walked slowly towards the library, distancing himself from Aurelia, who arrived a few minutes later in front of Arseny's room, finding it empty. 

"If I were an Incubus... better yet, if I were Arseny, where would I be?" Aurelia thought.
