Don’t hate on the author. Its up to them to decide how the story goes. It’s your fault if you are still reading. If you hate it so much, than make a fanfic about her ending up with someone else. (〜 ̄△ ̄)〜I personally like the plot developments. I still prefer Carslien or papa, but if the prince doesn’t hurt her in the current timeline, then I am perfectly fine with them ending up together. I just hate Jeiun’s ass. (╬ ̄皿 ̄)凸
I don't hate the author, after all they're the creator of the whole story; I do hate they've made the decision they made, however. And isn't it a bit hypocritical of you to say you hate a character after saying "If you hate it so much, than make a fanfic" ? Then you should just write a fanfic without Jieun yourself.

If she gets together with the prince, which I think she will, ill be pissed. Like are u kidding me, he kills ur child, u, your entire family basically, and u go and marry him cuz its 'a different world' the fuq. After she spent so much time practicing to be a knight and whatnot, i would call BS.
