Whew, boy. This was different.
There are quite a few twists in this story. Some people, like me, will absolutely love it. Others will not, wanting a more... predictable plot? How to put this without giving spoilers?
You could consider the genre of this story romance, after a certain point, maybe? The love interest definitely does fall in love first, and he is a handsome male lead, but... let's just say the roles and events, and the understanding of said things the reader comes to comprehend aren't reliable. Yeah. That makes sense.
If you get really into typical romance stories, you may want to read the spoiler before reading, because something happens later in the story that may make you angry, but if you like twists, mysteries, or are more hung up about the revenge part of the story, definitely ignore it. Things will be so much more satisfying going in blind.
Again, this spoiler (revealed around the 100th chapter, btw) is only for those who are looking for a healing, semi-normal romance, and don't like their emotions being played with.
Spoiler
This is a big spoiler, so consider it carefully before you read. There's more twists that make it worth reading, but this one's the big kahuna, and reading it will semi-ruin the first 100 or so chapters (only semi, though, as her biggest acts of vengeance were in there, too). Only read if I've already half convinced you this novel isn't for you.
We got Hans'd.
Yeah, from Frozen, Mr 'if only somebody loved you' Hans. For 100 chapters. It turns out, the guy who we are given all signs to believe is the typical, cold Duke of the North ML stereotype, is actually the villain. Yeah... after watching him court the MC who no longer believes in love for 100 chapters, rooting for them for her sake, since she desperately needs a hobby aside from revenge, he betrays everyone. Never loved her, actually hurt her behind the scenes a few times, and only wanted something from her. He's one of the unapologetic bad guys, but so much worse than her ex-fiance.
To be fair, we're warned early on that he's an actual, literal sociopath, but the 'untouched by emotions until I met you' trope made us not take it seriously, but he seriously has no empathy for others, and he's not a yandere who loves her in a sick, twisted way, either. 100 chapters, he courted her. That was two years in the novel, in order to use her, then kill her, then forget her. Once everything was revealed, he hit and stabbed her, while verbally abusing her. It was... uncomfortable to read.
Don't worry, though, there seems to be the true ML, who we thought was the 2nd male lead, Carl (who is both handsome and in love first, yay for tags not lying... eventually) to try to pick up the pieces.
Anyway, I love this novel so far. It's been unconventional, but that's fun, as well. Past the 110 chapter marker or so, it starts to become a little more typical, but there's still a couple twists coming. Truly everyone, even the scum of the earth, has their own point of view. This novel does a good job of showing that.
