It has something to do with Pride and Prejudice of Jane Austen?

Nope. And trust me, the male lead is NOTHING like Mr. Darcy... I think it's supposed to be some kind of reference to the way the female protagonist and the male lead have a sort of "love-hate relationship", filled with "pride" and "prejudice", as he is both her neighbour and arranged-marriage future partner, due to an agreement between their parents since before they were even born... But even that reference is too far-fetched because really, neither their relatioship, nor the couple's character and behavior are anything like those in Austen's Pride and Prejudice...
