I'm kind of on the fence about the start of this. I mean "supposedly" the main female was the evil king in her past life? And those three guys were her wives? Alright now here is where all the problems start.
First off the fl doesn't seem to have memories of being the evil king so basically she's a completely different person. You're punishing someone that doesn't deserve it.
Second, the evil king was apparently super smart, strong and good looking and the wives all fell to his ways but the second all that is taken away he becomes a girl?! This is implying that girls can't do shit. I mean I get that it's not something to get offended over and I'm not, I'm just a little annoyed that such a message is being portrayed. The wives who stole the kings abilities also became men so that also supports the whole "women can't have abilities". I know that's not how it is IRL I'm just saying that's what the novel portrays, and well I guess some people like that so whatever.
Thirdly, the flow of this chapter was pretty bad, I got confused a lot during some lines. That may be chalked up to translation though, not 100% sure.
Other than all this, I actually think it could have been a nice story if instead of taking the king's abilities they had asked for abilities greater than his so they can win against him. So in that case the girl would have been extremely good looking, smart and strong but the male leads would just be better at each respectively and there would actually be SOME competition you know?
Then again maybe it's too early to judge, this is the first chapter after all.
