It's a good story, I read the novel already after I read some spoilers here.
The key thing about this story, I believe, is that people are a result of their experiences. And the moment Tia went back in time, she changed what everyone around her experienced, so they all were able to become different selves from her past timeline.

I could explain why things happened the way they did in the past timeline that made me be a bit more understanding of the situation, but it would be very spoiler-heavy.
Like @Vivi said, keep your mind open, or not and avoid reading it. I personally feel like I gained from keeping an open mind and continuing to read, despite really hating Ruve in the previous timeline. But no one is forcing anyone :)

what a lame excuse.
After all the careful guidance he royal family had with the shit prince, he still got drugged and without anyone noticing it? Isn't he quite stupid for trusting the duke after all the teaching he had. Lmao
He's now attracted to the emotional Tia but the 1st TL he didn't because she acted mature. Quite pathetic dont you think? He should have known that you dont show ur emotions easily since he's royalty himself.
Where does being emotional like Tia's mother did end up? Oh right she's dead lol. And Tia's father being taught in emotions is still alive. The end looks like she will become the empress, what a shame, she still became the puppet of her world's terrible god.

There are quite a lot of problem with the basic plot and characters set-up and development.
What the is the difference in the 2-nd timeline that make the Crown prince (CP) a “wise ruler”, while he is basically a f*ck-up douchebag (well, more like loser) in the 1-st timeline. In the 1-st timeline, he trust the Duke Jena – the head of the noble fraction like a fool (and then casted away Duke Lars and Verita of the pro-emperor fraction). After a few years of work he ended up alone with no one to trust. Doesn’t that mean he is quite stupid? (How can an intelligent prince, who read so much, work so much with a father guidance end up like that? – the poison does mess up his temper and emotion, but not his rational thinking ability). Then, miraculously, that same stupid, narrow-mind dude become a wise, clever, decisive ruler in the 2-nd timeline. Because of what? Because he stopped envying Aristia? What a joke.
Second, what made Aristia love the CP in the 1st timeline? How can a clever, perfect, emotional girl (as everyone said) love a stupid dude who hated her???? Has he ever done something for her to make her love him that much? Yeah I understand that she has lived her whole life as his fiancé, but doesn't real love requires a real interaction? At least a smile, a favor or something of the sort.
Third, it doesn’t make sense to me that her father didn’t save her life, as well as meet her before, or even during her execution.
And many many more strange thing that don’t make any sense but to make the story more dramatic, more pathetic for Aristia in the 1-st timeline.
Aristia: despite her vow that she won’t love the CP and that she will inherit the family and all, the whole story is about her getting scared, getting upset, going back and forth between loving him or not, be with him or not, and other... Also, she can easily forget her friends. Why do I say so? She basically forgets about Allendis and Carssein when they don’t come to her =)))). Doesn’t that kind of made her a b*tch LOL.
Aristia’s dad: he loved his wife enough to ignore his family legacy, but was super calm knowing Aristia was poisoned LOL. He loves his daughter the most, he wants her to do the thing she wants, but didn’t try to break off the engagement when she said so (I can’t see his action as trying, especially after the old emperor died), also she said she wants to inherit the family, but he doesn’t want her to do so.

it made me drop the novel because of her treatment of Carsein that made me dislike her. Not because she didn't choose him, but because she clearly took him for granted and forgot about him when she was too busy being lovey-dovey. Even Carsein realized it and told her that he was sad she didn't came to check up on him after he was injured. He turned it into a joke of forgave her, but still... Girl, he is your precious childhood friend and one of the rare person who truly have your back. The least you can do is worrying about him without having to be told to.

Yea, she definitely made him a foul that time.
While I don't *hate* Tia, I do agree he deserved to be with someone who loved him the same way he loves her, and appreciated him and valued him the same way. I'm glad he found that someone and was able to move on from Tia. If anything, it would've been nice to get a side story of him being all lovey dovey with his wife or how he fell for her and stuff, it would definitely help readers see that he's better off.
should i read this or not? :(( is this story good? :((
