I can't agree more! However, I feel like Ruve's hatred is related to Tia's comments about her mother. Throughout the story, they have been giving hints on how, in the past, Tia used to talk about her mother this way. In fact, Ruve was indifferent about her in the past too, until something happened which might have not been about the appearance of Jieun. This is all pure theory though. Ruve clearly said so himself that he saw Tia's mother like his own mother figure.
He was indifferent but my theory is that he never hated her though I do agree that pressures as the Crown Prince is heavy especially when he keeps getting compared to her. He must have just wanted some form of affection in his lonely life and Tia's mother gave him what he needed. I also think he must have felt extreme guilt while at the same time frustration towards Tia. They were both quite young then and there wasn't anyone in his life he could talk to about his burdens. I think the current Prince is less burdened and shackled by his past feelings.
Exactly!!! He feels less burdened because he has someone that can relate to him which is pretty nice (人*´∀｀)｡*ﾟ+
Right? ( u w u ) It's why I honestly don't mind them falling in love with each other. He's turning out to be a good Prince so far.
I don't mind if she ends up with the Prince because from what I see, he never actually hated her willingly. In fact he was fond of her when they were kids. Plus after she turn back time, we see that he's slowly beginning to change and I do believe majority of his actions from the past life was all due to what's-her-face. I can't fault the current Prince for things that only happened in her past life with that Prince. That version of him can just go rot somewhere.
