And I think if you want to continue from where the webtoon is on, I think it’s chapter 47

Yes, Ren ends up becoming an important ally to her. He even is the one to find out that Lucia (glasses disguise name) is actually Veronica and then soon after finds out that she is a fake altogether. It’s pretty obvious that he likes her too. At one point he takes an arrow for her and nearly dies, and has protected her from enemies trying to kill her several times since he is considered incredibly skilled in swordsmanship.

Im not sure who you mean by OG queen I think you might be referring to OG princess Veronica (which go is substitute for). By that, then yes, at the end of the story, she is executed. And the prince notices that brown hair is actually Veronica on his own when fl attends this event as the princess/dukes daughter and the crown prince notices that they pretty much look the same and have the same atmosphere.

I don’t think the FL ever disclosed the fact that she had a past life to anyone. She ends up getting the real Veronica executed by the end of the novel, since Veronica and her dad (the Duke) basically attempted treason by killing the emperor and trying to usurp power. The Duke also does end up dying during the act of treason as Ren, Sian, and her knight all team up against him in a fight.

Oh ok. So Cecilia, the OG queen (she was actually the empress in the previous life, Elena, as Veronica, was the queen). Cecilia doesn't die in the current timeline. She and the Crown prince don't actually have any romantic feelings towards each other, just casual friends I'd say. Elena actually overhears Cecilia telling Sian that she doesn't want to marry him and does not want to become empress. The crown prince respects her wishes and agrees to let her go. In another spoiler comment, Cecilia actually ends up marrying Raphael, the painter.
I pulled all nighters twice in a row while having exams on both days + a super fried brain right now, but managed to read over 200 chapters (finished the novel but didn’t read the side stories) so anyone want me to spoil a specific event? Or any questions? There’s just so much for me to write if I were to spoil to entire story.
