I read some spoilers about Luca and i can tell you Luca actions are justificed.
Tell me more!
I wrote about it also under another comment, but let me tell you here so you don't have to search it.
Luca regressed, so now he lives a second life or something like this. On his first life he loved his uncle and saw him as a father figure, but his uncle before he died told him that he didn't love him and was only protecting him because of his responsibility
I think Luca was child starved of love, now in this life he was given love and care by his aunt, so he decided to protect her from getting hurt like he was in his previous life. Luca thinks his uncle isn't capable of understanding human feelings.
Ur very kind sir, thank u very much!
Btw is ln completed?
I don't know who is more annoying, grandpa or lucka.
Probably grandpa since he didn't know her at all, they know each other for few days, and now he tries to control grown up woman life.
I don't rly remember what is lucka deal, but he isn't far behind grandpa, is he in love with his aunt or something? Seriously it's wierd af.
