Yeah, he got reincarnated
It would have been best if you put spoiler warnings for the readers who dont enjoy getting spoiled but I do wonder why is Luca trying to stay with MC aka his aunt?
I tried imagining possible scenarios such as him wanting to make his aunt deal with the possible events in the future but I don't know how that would be effective since he only knew his aunt as a greedy woman who sold him to the duke before MC reincarnated as her
Oops yeah, I should've out a spoiler tag. I only thought of answering the question. Sorry to all of you who didn't want spoilers.
is it possible that he wanted to change his aunt’s fate? and his aunt herself and make her a better person?
He wants everyone to be happy. That was his wish in the first timeline with the use of the goblet (Vintervald's family treasure)
But why? Not that it's bad or anything, but in the past life didn't he resent his aunt? So why would he want her to be happy?
I wonder if Luca also remembers his past life? But that raises more questions as to why he would stay with his aunt.
