I read in a spoiler that lucas made a wish to the sacred cup after he arose to the seat of duke winterwald and retained his memories. While judith was actually the real judith and not a transmigrator. I forgot why she has memories tho. And the reason why he doesnt like rudi for judith is because altho rudi was a benevolent uncle, he also knows rudi doesnt really love lucas but rather did what he did out of responsibility. So the rudi lucas knows is someone who is unfeeling, coldhearted, stiff man who lucas thinks isnt capable of loving someone. Thus he doesnt want a man like that for his auntie. And i think lucas knows judith tried to save him before but was killed so he never hated judith

No she did. At first she gave info on luca (just realized that i wrote lucas lmao wrong person) to the brown hair man right? But she didnt know he was trying to kill luca. When she realized, she went back to find the man but as she was trying to call his bullshit ( i think she was trying to expose him not too sure) she was killed by him. Thats how judith died in the original. This is my assumption, but maybe that is why she has memories of the past due to her regret of being a bad aunt to luca.

I read it in the forum spoilers. Hehe sorry for dumping a lot of spoilers on you, i hope u arent the kind of reader who hates being spoiled cos ive attached an excerpt to fully explain in detail. Also, I was wrong when i said she sold luca's info at first, my bad. I read this spoiler months ago and forgotten some details. Also her death was flashbacked in chapter 34. This part also explains why Luca was sort of attached to Fl from the beginning.

But heres an excerpt: But he realized that Judith eventually did stopped disliking him in the past life, because when he left for Winterwald, she secretly gave him her only portrait of her sister. In fact her hate turned to Winterwald, so past Judith went to Franz to get his help to get revenge against Winterwald. Judith at that time didn't know Franz wanted to kill him and take over Winterwald. But later on, Luca realized Franz changed his plans on killing him because Judith had fought with Franz to make him change his plans. Luca knew then, Judith didn't really hate him.
I think Luca used his wish to go back in time to fix everything or he read the same novel as Judith. It has to be one of these he knows what's going on too but I don't get why he said that about his uncle. In the novel he loved him and died for trying to protect him.
