As novel reader from this manhwa , I can only give you spoiler about the ML and is Arsian..... he's also one of the reason why Camilla still choose to stay in this world even though she been given a chance to go back to Korea or modern world .
In this world she will receive so many titles on her . And the real enemy of this world is someone unexpected.
SPOILER
So I read up on spoilers, because of this comment and if anyone wants to know I will post it down here, so look at your own discretion
So the villain in my opinion isn't someone unexpected, I think it's quite a common trope in stories like this from what I've read
No, it is not Ravi or anyone from MC's immediate group of relationships
It's actually the emperor, so I guess the father of the crown prince
There is more to it from what I've read, so if you're interested, go to novel updates for the spoiler thread
who’s the ml
