Please don't listen to the negative reviews, one of them only read 5 chapters and the real plot starts from ch 8. This is one of my favourite josei manga right now, it has great art, good characters and an interesting plot. The series tells the story of an orphan girl named Nina, who is forced to take the place of a dead princess. She develops feelings for the second prince of her country, but in order to save his life, she decides to marry the crown prince of an enemy country. However, her potential husband has no intention to marry her, in fact, heuses the bride candidates as political tools in order to attack their countries. With no one to rely on but herself, Nina has to make her own decisions and try to survive in a new environment.

I've seen people calling Nina all kinds of bad names, but people have to understand that she's a young girl who's only just learning about the workings of the world. She grew up in the slums, lost her parents at a young age and had to steal in order to stay alive. She believes that one's destiny is not written in the stars and it can be changed, because she doesn't want to lose more people dear to her. She's around 15/16 years old at the beginning of the series, that is when she has her first love, but she doesn't think she'll see him again. She resolves herself to stay by the man who has to be her husband, she teaches him how to express himself and share his feelings, they have vulnerable moments together that's a start of a new love. But Nina's first love appears again, and she gets confused. And it's totally normal, she's so young to fully understand herself and her feelings, in fact, she cannot even imagine herself in a physical relationship with either of them. The first kiss that SHE initiates is much later in the story and it's a kiss on the cheek. It's not until she learns much more about the world and herself that she starts to experience a more mature love, one that has the potential to grow into something more. Which leads me to me next point (minor spoilers ahead):

Another negative review said how Nina will choose Az in the final arc. I don't know what led that person to believe this, but it's not true. While there's no confirmed male lead, it's kind of obvious who has Nina's heart, and (spoiler) it's not Az anymore. Nina clearly thought about how Sett will be the one to be at her side when she grows old. She talks about her feelings for Az as if they are part of her past. Right now, the main focus of the series is not this anyway. There's a lot of interesting lore about gods and Nina's eyes, and everything is slowly coming together. There are plot twists that were foreshadowed ever since the first chapter.

I enjoy the manga so much so please give it a chance and decide if you like it.
