I think FL doesn't know the third prince be slave trader. I don't know how the author think, maybe he/she think we will think how cool of ML because he has mysterious secret side of him but when I first find out it made me disturbed honestly. And I think he sold mainly kingdom's people, people of color are so rarely.
Exactly as a prince and he’s supposed to be the better option compared to his brothers, it’s weird and down right wrong if you can fathom selling another human being and placing them in a cage i wouldn’t trust your moral judgment when it comes to ruling a country. And on top of that referring to people as barbarians and so on is so vulgar in itself just because their culture is not the same as your own. We see this soo often in manwha that it’s honestly become one of those things we just accept more times than not it’s always people of darker skin and they always look the same, just for them to be treated horribly throughout.

It’s quite strange how almost nobody is talking about how the third prince (mc’s fiancé) is literally a slave trader??? Like he’s literally selling and kidnapping people. AND the enslaved people are people of color, who are depicted as having no manners, rude, brutish, etc…like maybe I’m crazy but this entire manhwa feels racist as fuck. And the fl doesn’t seem much better, we got a little bit in her thoughts about how she thought the practice of slavery was gross but we don’t see her doing shit about it. And then we saw her calling the fuckass uncle or wtv a “specimen” of the same race, and even brought up his “breeding”, implying that his culture is the reason he’s a prick. And then she ended up paying 1.5 billion anyways (albeit with the necklace thrown in), far more than the 500 million she was offered first. Like bruh. And how does the Kaluta tribe not notice the fact that hundreds, if not thousands of their people are disappearing into nowhere every year? And when they do inevitably notice, and discover the empire is behind it, how will the author write them to react? Will any compensation, if offered at all (or if it’ll just be brushed over as part of the plot) be enough for the crime of fucking trafficking hundreds of thousands of people for god knows how long? Also the fl lowkey pisses me off too, she’s annoying and the author wrote her as a Mary sue so everything is going right for her in this life. Anyways I might add more stuff to this comment as I keep reading lol
