ABORT ABORT. This mainly revolves around the empress and the mistress.The prince is basically a side character. It got licensed so the project got dropped, but there's so many other better series out there as @PZcolo mentioned. Loved The Villainess Reverses the Hourglass.
I actually had the same mixed feelings in the beginning chapters, thinking it was another boring repetitive reincarnation manga... but I admit it gets good as you continue to read it. It's the first manhwa I've read with a clearly mentally ill male lead with a capable female lead and a big btchy antagonist. The story rly got me invested in the male lead's past and trauma, I rly wanna know why he was so stuck on that btchy redhead. He seemed as if he would believe her at every possible chance at first, but in the recent chapters, you could actually tell that he was capable of thinking rationally and weighing things over. This is just my initial rating.
Read if you enjoy being infuriated by it all the time.
I would recommend reading "The Villain Lives Twice" or/and "The Villainess Reverses the Hourglass" instead if you haven't.
Reincarnation re-do with a "cold" husband, and his Waifu, who is the generic manipulativy beauty, with no character devleopment thus far
other than nutjob w/ delusions of world conquest or something. She has literally no motivation or character outside being a power hungry psycho-bitch, who lives only to stick her claws deeper into her husband/his position, and no distinction has been made on her part for what she actually cares about. I have no idea what her motivations are, but she abuses her servent who seems both loyal and USED to this behavior. And the guy in all this is supposidly not a moron, but hasn't noticed anything off about her up till this point. Honestly i'm more interested in hearing about the servants backstory than the mistress, and how this very obviously nutjob earned such devotion.
The art is mediocure, I've seen several works in this style, and it does everying just okay. Nothing is really bad, but nothing has been done to really make it come together, and coupled with boring character designs it's actually just a bit off putting. A few interesting choices here and there help it a bit, but they remain isolated among the blandness. The entire plot is super weak thus far and pretty apparently is going to require the husband to be biased in spite of logic or reason in order for it to keep going.
In summary; The protagonst is okay, the art is mediocre, the side characters are bad. There are better romantic stories with similar premises out there.
