For the first question, i think its because he thinks its interesting or something? Maybe he thought, 'this didnt happen last time, might as well see how this goes.'
Or maybe he sees nice judith as an opportunity to not become fully depended of his uncle or something, since he currently acts like he is displeased by his uncle.
From the spoilers that I read:
Luca is the regressor. He rewinded time so that he can change the future so that everyone can be happy.
While Judith is the real Judith from the novel. But in her case she died, then reincarnate to Korea, and transmigrated to Judith when the time reverses (or something along the line)
Hahaha...more or less....
From the spoilers that I read, Judith actually chapter Luka because Luka took her sister away from her or something along the line. And Luka resembled Jonas which fueled her hatred. But in the end of her life ( in the first timeline), she actually loves Luka but she's in grieve
1 . What is the reason that luca show affection towards judith !? Even though in the past or present she was so qruel to him until just resently !!!!!
2. How come duchess and uncle changed !?
