Since super optimist, stupid girl over here, Julia, is following how the book goes and is in love with the prince. How will she react to the ending of the book? I mean especially since it is going to be chanced to her crush ending up with Yulia her so called rival/ villain.

Most likely not, judging by Chapter 4, because she will be pursuing the prince as she may think that "the publishers got my destiny wrong. I'm supposed to end up with the prince!" And as these stories go, Julia (is it her name? idk I call her Bitch-chan) will do something outrageous, and either gets stripped of her newfound nobility, joins hands with the evil kingdom or some shit, or is sent to the dungeon and dies.
Honestly, I can't read everything in Japanese, and I can't find raws, so this is all hypothetical. I do not know what will happen, and I am basing my theories on common tropes and instinctive decisions.

Imma draw myself in there with an eraser and first of all, expose the heck out of you. So that they can give the beating to you, for me, for we. and after she has gone through the hell she deserves, I'm going to take my eraser and erase her. When I am done, I will go back to my own world and finish my tea.
why can't he just confront and ASK.
He did but the timing was so ridiculous, they both misunderstood each other. Muyeong was like “a secret affair between someone from the publisher and the author. That’s it, right?” And Seonho went all gung-ho and agreed, “WOW HOW DID U KNOW” plus the name of the editor is close to his name so he thought Seonho wasn’t murmuring her name instead of his.
