It's kind of tone deaf , since it's based on slavery and since black people suffered , were tortured and died due to it, like from the premise it seems like taming the "unruly slave" after freeing him from slavery and if it got popular it could(definitely would) lead to romanticization of slaver/masterxslave and a lot of readers especially non poc will downplay the issue of slavery (quite frankly a ot of them are doing that even now) so yeah , it's incredibly tone deaf and insensitive to use that as a backdrop for any literature
Basically its like romanticising a trope that's inherently wrong a ship were owner x slave is bound to have power imbalance ( not saying this isnt possible but this is a really sensitive topic ) this is a really heavy topic that not even Americans ( the country of this history) get right so for a korean author to profit of something that is still used by racist people is really wrong

I'm not a Person of color/native and we don't discuss this in schools, because we have our own shitty history to deal with ..
- I'm asking genuinely..
What is wrong with this? The comments are making it more confusing for me..
