We are seeing some hints of plot points:
- What's up with the golem? At the very least, it implies that there's some background connection between Hyudor and Renee.
- What's up with her former Master? Presumable someone quite competent. What was his interest in and plans for Rene?
- (BTW, remember that Hyudor is not the demon lord, but rather the leader of the demon lord's army.)
- What's up with Heroes? They only appear every 100-1000 years. Very little is known about them. And the scarce information sources are untrustworthy (rewriting history probably).
- What's up with Rene's hair? What an odd little detail that her hair occasionally has massive growth spurts.
- Is Rosa avoiding Rene? Why? And she met Rene early on in the story.
- Renee can't understand that people like and want to care for her. Will she overcome that?
- How was Rene sent (as the hero) the castle in such a haphazard way? Seems like she was just thrown away (which seems insane or incredibly stupid). Or maybe her former master arranged for her to be sent there, expecting that Hyudor would treat her well.
- Is there a war between human and demons? Other than Rene's mission, there's been no indication of one.
- How good a fighter is Rene? We've never seen her fighting. Also as far as we can tell, she's no longer maintaining her training.
