Can someone explain what her past brother did to her ? Im a little confused

It's portrayed very vaguely, so it's really up to interpretation.
Some say nothing really happened and she just felt overshadowed and manipulated by the brother. Others believe he abused her on top of the manipulation.
But frankly the author never explains explicitly.
I'm of the belief that her past with the brother is of a more severe nature, due to her actions and reactions painting a picture of a severely traumatised young woman...
But I also believe that the author is very deliberate with leaving the past up to interpretation, so that a younger audience aren't shocked by the story, but an older audience see the darker themes of the story.

God why is he so worthless??? Like dont get me wrong obvi we love edi, but damn he hasnt done anything right this whole book. Whyyyy is he so garbage?? Just tell her you love her once and everything couldve been solved. Its not that hard to stay away from chicks,aka luna, who wanna fuck your brains out. No hate plz i do love thos book im just frustrated that my poor baby is suffering bc her husband is a tsundare.

Everytime i start to find the prince favorable i reread the first chapters and I realize what a horrible man he is. Team carson for daya

Or “in your past like you massacred my family.” Yeah. Ok. Idk what your talking about but that wasn’t me. No offense but I dislike half of the people (commenters) who can’t divide the two.
It’s like judging you on another universe, cause technically, after she reincarnated she caused a split in everything. They’re in a different path COMPLETELY to what they are on now. Yeah sure without her “awakening” and having those “memories” they would still turn out the same (I guess), but she is the biggest variable of all! One person can do a LOT
Such as change people and save people... her newfound confidence, not only in herself but also in her family, is completely different to who she was before. She was a stoic, serious, depressing girl with no real substantial platonic love between the prince and her. Now it’s changing because she has changed.
If you respect yourself and are brimming with confidence, not only is attractive and charming, but others will also respect you too. Without a doubt! Thus not only changes how others see you but of course how they interact with you. SHES A DIFFERENT PERSON, so why can’t the prince be?
I find that bias and actually very offensive...

And yet it doesn't change what happened to HER. If someone slaughters my family--then after a while they change and I change--I'm supposed to just forget they slaughtered my family and wanted me dead? I may figure, "Hey, dude, wish you well in your new life, buh-bye." It's hard to look at the face of your father's murderer and your murderer and say, "Forget the past." Some can do it. I suspect most would feel trauma.

Of course not, she’s totally entitled to have trauma, and she does. The manhwa is realistic about it too. However, I could understand THE READERS (strong negativity) towards the prince IF she’d been reincarnated as a DIFFERENT person in the SAME timeline... but she wasn’t. She was BROUGHT back into time BEFORE anything happened, or probably WHEN everything happened, and has that chance to change the future (which she is).
Cause now she’s a young child, fathers still alive, she has that opportunity to reconnect with her father (whom she had previously wondered if he even had any affection for her), and now is making friends (when before she had none). Has the opportunity to KNOW the prince from infancy and to understand him.
I’m just not so fond of the majority of the readers, my personal opinion.

No one is denying her right to PTSD, just as no one is getting angry at her for trying to change her future and wanting to nullify the engagement.
What we're saying is that it's not right for us as readers to hate the Prince just because of what an alternate version did to Tia and her family.
We're just asking for everyone to keep an open mind and follow how the author will take Tia on a journey of getting stronger and finding forgiveness.
Also, I don't know about anyone else but I'm looking forward to seeing how the author is going to make the Prince grovel and earn Tia's trust and forgiveness. Because like I said in the beginning, Tia does have PTSD and it takes A LOT to get over it.
If the author does a poor job of it, then you're absolutely allowed to rant and not like it, but for now give the author a chance to tell the story.

Why not? Why is it not right for people to hate him for what he did under other circumstances. THat was him. That was what he would do under those conditions. What his character does given specific stimuli. It's not very laudable, at least what we saw. It is riddled with prejudice without fact-finding and various counsel (which a king should do). It was using one person and torturing another for self-benefit. So, that was WHO he was to her. And if a reader wants to hate him (to this point), why not? I imagine the author has sympathetic stuff up the wahoo for us, and that will change opinions. But when what he DID DO is so fresh, let them hate him.

Bruh hop off the princes dick for two seconds, im not saying he isnt a new man who shouldnt be hated. Im saying if i had to look into the eyes of the nigga who killed my baby and my father. I could NEVER forgive him. And i know if any of you were in this situation, you wouldnt have the will power to not hate him either. Just reread begining, ik its not the new him and its the old him. But damn that shit is brutal.

Does the Prince actually love Irene? because it says that their lovers. so why is he talking to the MC then, doesn't that make him a cheater?? I know that Irene's evil and that he should dump her but it seems like they're actually together??

Well he's supposed to be the next Emperor and Irene and MC are both I guess you could say "fighting" for the title empress but being a Regina makes them both capable of being at least a queen and the only reason the prince was rude to MC in the beginning was because how her father didn't support him as the heir but now that the prince spent time with mc I think he has a thing for her now maybe

I also thought that he a cheater too but it's seem...he,who doesn't good eyes unlike 7th prince probably thinks of Irene as a person who could help him to run the country which why both him and Irene become a lover. And Irene pretty much used him to climb her family to be a royalty. ╮( ̄▽ ̄)╭
My opinion ah.

If that were the case then that wouldn't explain why the prince is constantly helping Charti in the later chapters and not lending a hand to Irene past that one scene during the ball. As I've said, we're reading things in Charti's eyes. Her doubts reflect on our opinion on the prince even if they aren't right. It gets clearer as we go on. But despite all that, Charti's not romantically interested in either of the princes. She's also not in a love triangle with Cailanden, the fifth prince. She only wants a platonic relationship despite knowing full well the other might be interested in her that way lol.

Why would he doesn't need to help Charti? (⊙…⊙ ) In my eyes, he kinda innocent unlike other ML in other mangas similar to this. (▰˘◡˘▰) So, I assumed he will go for justice than defending his lover. Moreover, his brother's reputation is at stake(is it correct word? ) at that time. And what I mean for my previous comment is both of them became lover not because of love or smthng like that but one thought she could help him while other one used him to climb as empress. (づ ̄ ³ ̄)づ Yes, we read it in MC perspective but her opinions are not only based on her perspective but in rumors that she heard too which why I thought he looks cheater but it's seem not because it's not love for them to be a lover but other reasons.
Did my words understandable? (⌒▽⌒||)
I have a lot of step brothers, and they are family to me regardless of blood relation. I understand that he loves her, but its kinda cringey, like they are family she keeps calling him brother. Ugh
It's just that you see them as family while they dont
Well technically its 2 different situations since those are you blood related siblings while gerald was adopted meaning he shares nothing about the family except the last name but I can understand what you mean because if I was raised with someone who is like a sibling I wouldnt see them any other way
That is why I said .... familycest
Its uncomfortable #-.-)
I think the angle here is that he likes her (romantically) since they met, so he literally never, not once, thought of her as family but as a romantic interest.
From her perspective things are different, though. Can't say anything there, she really keeps thinking of him as a brother, but she suddenly has doki dokis for him? Seems strange.
