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
I wonder if Luca also remembers his past life? But that raises more questions as to why he would stay with his aunt.
