So Luca finds out later that even tho his aunt was a bitch to him she actually sacrificed a lot for raising him. Also dies protecting him. Aftet the aunt dies he finds out that she was protecting him in her own way.That's why in this life he ignored her at first because he didn't want to drag her in his problems but then he noticed that she changed and so he takes her with him so that he can protect her and also give her a comfortable life.

And that he found out that Ruediger only protected him because Ruediger thinks of him as only his responsibility, that's why he's kinda mean to Ruediger in this timeline. But imo Ruediger only said that because he's unable to understand feelings like love because he didn't got that all his life and thinks that he's being extremely protective of Luca bcs of responsibility
Yh we know Luca probably reversed the time but the question is why? His previous aunt never did anything to help him so it cant be because of her. Didn't he earn a happy ending? Or is there a grudge that's deeply rooted he couldn't let go off? He didnt looks vengeful enough tho. Mhm maybe he wants to save Rudegier the most but then why pick a timeline where he could be possibly abused and neglected by his aunt again. Maybe he didn't end up being specific then.
