It's just my opion but I think what happened in their past life wasn't mainly because of her. It was all the duke's (which I think the main villain in present life) doing and also because people as well as the crown prince favor her more than tia that it made tia suffer. Yep, really the crown prince is also at fault... well he is doing good now tho. Then the issue right now why she wants to prove her self is I think because even after tia die (past life), she still couldn't make the crown prince completely his and I think she realized how dumb she is in her past life. Most likely about her pride and wants to get the prince heart. Some spoiler says that when Tia died the crown prince realize he really love tia from the start, just he got brainwashed and jealous of tia. I dunno if it's true but I heard he even commit suicide later after tia's death? Correct me if I'm wrong. Maybe that's also the reason why that black hair is now trying to be 'better' than tia right now.

lol compete? NO. She wanted Tia DEAD. She was going to poison Tia because she thought that she was the main protagonist but she realised that now she is the Villainess and that's what made her change. Also PLEASE stop blaming Ruve guys!! Everything EVERY SINGLE BAD THING that happened to Tia was all Duke Dickhead fault. Ruve loved Tia but he was jealous of her growing up because she got the love he never got and Duke Dickhead told him that she was of peasant blood too. Duke Snake whispered a lot of nonsense in Ruve's head which is why he and Tia had a rocky relationship. Tia also made it rocky because of her cold demeanor. She was not the same Tia that she is now. Ruve never loved Julien he was infatuated with her because of her warm personality. He was devastated when Tia lost their child. Duke shithead told him that she aborted the child when in actuality he poisoned their child. Ruve didn't go to see Tia because he thought she had killed their child because she hated him and he was grieving. He never killed her dad he had her dad locked up as form of revenge plus he wanted her to leave the palace he thought she was suffering and never wanted that for her. But she went and stabbed him so he was pushing for her to be EXILED but the aristoshitheads pushed to have her executed and Ruve literally had NO POWER despite being the emperor.
Everyone "loved" Julien because of her "warm" personality and they thought she was competent however when they realised just how incompetent she was that love turned to hate real quick because she literally was of no use and .the empire was going to shit without Tia. People were mourning Tia and wishing that they never executed her and thats what made Julien decide to come back and fuck shit up for everyone. She blames Tia for her downfall when she was the one being fucking useless and not putting any effort into learning anything.
Everyone is to blame even Tia because she didn't have to clean up after Julien but she chose to do it. Albeit she didn't really do it for Julien she did it for the empire but that was her downfall. The Duke and his party felt threatened by her because they could not control her like the figurehead Empress. They knew that Tia had all the power despite being a mere queen. They needed to get rid of her to control Julien. However no one knew Julien was gonna be that useless and the empire crashed and burned.
I don't remember much cause I read the light novel like before I changed to this phone I currently have and I've had my phone for couple months almost a year now. Also I swear I'm not arguing or fighting with you guys I just GENUINELY FUCKING HATE JULIEN and she literally makes my blood boil.
Can someone pls tell me if jueun will continue to be a bitch or is she doing it for their sakes? Because she also went back in time right? So she fucking KNOWS all the horrible things she did to Tis. Just spoil me pls so I can really decide to hate her or not
