What's Wrong with You, Duke?

I don't ever remember how I found this manwha, but this plot is really something else. Going against the flow "i reincarnated and whatever", it was nice to see something diferent. I admit, the start was very sudden. Erin, our main character, almost gets killed by duke Rowan in a war. However, a magic circle appears out of nowhere, attending Erin's wish to stay alive and she ends up getting married to said duke. What surprised me was to see that one year has passed since that moment, but really, that's when the story really begins. Because after one year, the magic starts to fade, andthe real Rowan, the one who is annoyed for having his free will taken from him by a spell, starts to show up more. And damn, that guy is great. He tries to regain his life while Erin tries to find ways to reinforce the magic and not be killed. The manwha has a great pacing, with a slow burn relationship. It's great seeing Erin starting to fall from the real Rowan, not the "perfect" and clingy Lex of her dreams. And is even greater to read Rowan falling for the one he once hated so much. Rowand is strong and determined, while Erin is gentle and despite not being very smart, at least has good instinct regarding certain people. So, why didn't I gave this the maximum score? Well, the story takes a great turn. The plot twist was really great and surprised me so much, that I couldn't stop reading until I finished. However, it should had endend in a certain part of the story. After that, was a cute story, but I felt like Rowan personality changed so much. So, that was a great and fun read. Fully recommend.
