By the end of the show, we see that one of the story's themes is about the dangers of prejudice.
Not just everyone's prejudice against the ML, but also the FL's unfailing trust toward the ML's alter-identity, just because she believes he's "good". Even the second ML railed against the unfairness of it all; his one misdeed (of not instantly trying to save people in the fire) is judged much harsher than any of the main ML's "crimes".

One of the characters who had to learn this lesson the most was the FL. If the show was trying to portray the FL as being rational, that her actions were based on evidence, then she wouldn't have needed to learn this lesson.

Can we also touch on the fact that the ML didn't approach the FL with his alter-identity with the intent to lie to her; she was the one who latched onto him? Considering her blatant hatred for ML, it makes sense for anyone to stay mute as to their true identity. Not to mention the fact that she's constantly plotting to kill him, too.
When the identity reveal happened, the story immediately focused on the ML apologising to the FL for lying about his identity; at no point in the script did the female lead apologise for trying to kill him.
I'm sure this was done on purpose -- in fact, as the drama progressed, I started to agree with some of the other commentators about the FL being rage-bait; she's written that way as another layer on this satire cake. She's not supposed to be likable.
Taken in that context, you can say that if you like her character, you're watching this show a little too seriously, lol.

She doesn't know, she assumes. She's glanced at the script and believes she knows everything, including everyone's motives.

She enters into a world based on a script she's read, and proceeds to change everything. Okay, good, no argument there, try to survive.
But then she discovers that even though she tried to change her fate (like not going to the garden party, or cussing out the prince the moment she sees him), she couldn't change crucial scenes (they still share a kiss). Her body follows the script even though her mind is rebelling against the very motion.
Anyone with a lick of sense would realise, hey wait a second, not only did I not want to kiss the prince, he didn't want to either, and yet, we kissed. Why would that be, I wonder?

But that thought doesn't cross her mind. Her thought process remains on a surface level of, "I want to survive, he's the bad guy of this script, I should kill this guy."

I'm not asking for the FL to jump into the ML's arms the moment she meets him, but at least rationally look at the situation around you.

Look, in the end, it doesn't matter; this show is supposed to poke fun at terrible c-dramas, so it makes sense that this script is terrible (if taken at face value).
I guess the script just didn't lean far enough into the satire after episode 2 (or it was too obscure for someone like me), so I started watching this as if it were a serious period drama.

ep 8. I hate it when the FLs are made to be stupid and yet ignorantly ploughing forward as if they know everything. And yet everyone still bend over backwards to cater to their whims.
The show was funny to start with, but at this point I kind of wish the FL would just go away.

The ending was interesting... never watched an isekai where the story has the main character develop feelings for the book world, learn to want to save the book world and start to see the book world as real, and then transport her back to the "real" world as if that should be her happy ending all along.
