I'm sorry, I don't actually know the specific 'Nicolae Miu story'. There could be many people named Nicolae Miu and without more context it's hard to tell a particular story.
The theme of adaptation is prominent. Iruma has to adapt to the completely different and often crazy rules and customs of the demon world. Also, there is a theme of defying expectations. Despite being a human in a world of demons, he manages to exceed the low expectations others initially have of him and rise to great heights.
Clara is an important character. She is a very energetic and somewhat unpredictable demon. She befriends Iruma early on and is always getting him into all sorts of strange and fun adventures. Then there is Sullivan, the demon who bought Iruma. He acts as Iruma's grandfather in the demon world and is very powerful and protective of Iruma.
In the manga, the relationship between Iruma and Ameri is complex and evolving. But as of now, it's hard to say they end up together. The story is still unfolding and anything could happen.
