I love how this one shows character development especially with the ML. They begin to trust each other before falling in love. Like him taking her advice or telling her his schedule. And even though he does have concubines while he's with the empress (which is a trope I usually don't like) it's more like they were forced upon him and it was required to have them there (like for trade, spices, weapons & other resources). He doesn't interact with them much and the 6th one was still a virgin. Sasha probably is too. I also love how to other nobles and rulers their seen as badass villains but to their people and the public they're doing great things.
The only confusing thing is with so many translations I still don't even know the true FL & ML's names. Her name goes from Ras, Lars, Larcy to Lass. And he's been known as Zepon, Jepon, Jervin and some other names lol.
