Duke i love you.... But please. Just drop the "She use to be a princess thing." its obvious from what Chloes said she was miserable being royalty and loves medicial herbs. He's so stubborn i swear.
I get it though. From what i can tell, the duke doesn't want to believe that everything he has and faught for was for nothing, because if a war slave who was once a princess can be the happiest she's been without those riches, than what kinda life has he lived and what has he faught for?
But this might just confirm Chloe is actually his half sister. Babies were abandoned alot or sold to slavers back than so its not a big jump. If she isn't his sister i hope we get to meet his real sister soon.
Another great chapter and translation tho, god this story is amazing to analyse!!!
