I loved got, so the fight for power is not the problem at all. Also, the story never seemed unrealistic to me from that point of view, my only problem when we talk about realism was the second prince's character, which is kind of all over the place.
The real problem to me, tho, is the characters that are unlikeable for their personalities, not their choices. They are really unlikeable XD I have a really hard time trying to find a redeeming personality traits for anyone. It makes the reading not enjoyable and makes me not care. Maybe in the long run the story will improve but for now things are not looking great.

Wow that's one hell of a question. Ahmmm I'm fine with the dark things like saezuru tori wa habatakanai, and I also enjoy simple minded shoujo/josei - the only one that comes to mind rn is mangaka to yakuza? It was really something else XD
But if we are speaking of something with a more similer note to this one, maybe the villainess reverse the hourglass, when the pretty awful female lead is rivaling with her much worst sister that killed her in their prevoius lives. Or maybe the feel of king maker (first season tho, the second is not at the same level) in which the characters face an awful villain that ruined all of their lives so much that it's impossible not to get behinde them. Or the character dynamic in raisawa tanin ga il, that is great cause the leads are one the same side but not. Also as much is we go into the plot the characters become more rotten and that is greattt.
Anyway all of those last menstions included anti heros that are very likeable from all kinds of reasons/maintained the readers through other means, and honestly I think here they tried to go with an anti hero theme but failed.
I think I'm done, the unlikeability of everyone is just dreadfull at some point. I feel no excitment reading episodes. I tried getting into the new chapter and then just noped out XD
I think it has potential, but the characters, the general feel of it and the pacing are all kind of... lacking. Also personally it seems like the story is scared to go really dark. It's trying to play on the bad boy-bad guy line but it dosn't gain anything from either side. It needs to pick one, you can't eat the cake and keep it too. The second prince is not just an asshole, he is a murderer. He is a bad person. But it seems like the change he had ripped his personality to shreds. It's not a men that changed, it's one who got his memories erased. Maybe it has an explanation further into the plot but it feels off.
Also the FL. I tried. I really did.
