Tbh, i thought the girl was being sincere in her apology. If she was sincere, it would bring in a whole lot of complexity, I think. She said that thinking back, she didn't understand why she hated Yeoryeong so much and why she did all that - if it was sincere and not a lie, doesn't that mean that she was 'compelled' to? She's the one that did it, but how much of the emotions that led her to do it was hers, if she herself doesn't understand why she did all that? Obviously the rules of internet novels has had influence on the main characters and their specs, but does it influence the emotions of the minor characters to lead to cliche situtions like the protagonist being bullied???
If so....what does that mean for Dan-i, who has suffered so much but in reality it all could have been because of Inso's Law? would she be more hurt or feel despair due to the added evidence that everything in this world is fake, or be less hurt, because it was all 'predestined' and there was nothing she could do about it? Regardless , her trauma from everything that has been done to her remains.
