Ok so far what I've understood is that the 2nd psycho prince has been going back and forth between timelines to change the future, in the timeline they both fell in love was probaby where she became the duchess and her brother became a knight. So he finally changed something I guess? She will not die anymore I guess? then she hates the psycho prince now (totally understandable), but then this is just a sad end for the 2nd prince, will she really fall in love with him again? It would be pretty weird to fall in love with a person who hurt your family. But maybe if she gets her memories from those past timelines she will understand and the story might change?
And now this 1st prince, I have a feeling he had part in lamia being dead in the past timelines 🤔 I feel like he will be a villain, or maybe not maybe he is the 2nd ML/love interest.
There are still a lot of questions unanswered. But I'm looking forward to the next season.
Thank you for the translations!!!
