My theory atm is that he is reincarnated and is living his live again.
Idk how or why, but at the end he dies somehow, maybe alone and hurt and gets another chance to live a fullfilling life, saving the people he loved (his uncle specifically)
Thats how he knows what happens and how people are supposed to be (bad aunt, loveless uncle)

Pretty sure he used "the wish" to go back in time (regressed), to make things right (he did become a duke but at what cost...) so that he wouldn't have to kill unnecessarily, although I'm not sure if he actually wanted to save Ruediger as well because he was hurt by his indifferent attitude towards Luca. I feel like Luca just wanted another chance at happiness (which ultimately came in a surprising form of his Aunt's new and loving behavior that she previously didn't have)
Who is Luca??? It’s obvious he is not the same as in the past!!! Who is he???
