It is an interesting story but feels more like a fantasy romance novel than a LitRPG. I can’t figure out who’s the main hero of this story, the MC or the Demon King. The MC seems to become a submissive support character for the Demon King as the story progresses, which is a little disappointing. Narrating is often done from the MC’s point-of-view, but will sometimes switch to the Demon King’s, and occasionally go to the third person. All that aside, I love anything with a full voice cast, which helps make up for any shortcomings in the story.
