I understand it's mostly due to the original plot's control over the characters but it's still hard to read. Like for example when MC gets accused of staging her own poisoning. ML barged in and accuse her then sidesteps (maybe due to guilt) but in the end do nothing while MC writhe in pain.

She tried to kill MC like 10 times and literally committed a mu*der! But guess what?

HE LITERALLY LEFT MC TO DIE JUST BECAUSE HE BELIEVED OGFL AND GOT CONVINCED MC WAS A TRAITOR THEN PROCEEDS TO BE MORE OF A tr*sh BY GETTING MC ARRESTED WHILE SHE WAS f*ckING INJURED

only to get disappointed

The fact that she still had the idea that no one truly loved her and that Killian only felt pity for her makes me grieve so much and I'm so glad she was able to have her happy ending. Once she realized that people were on her side she truly gave them so much love and it makes me fall in awe at how many people she didn't realize were on her side since the beginning of the novel.

In the side stories it is fully confirmed that Lizzy had complete control over ML in the beginning Once Edith started to charm ML, Lizzy started to lose control of Killian. I would say she started losing control when Killian found the bruises on FL (Around chapter 30). Must I also say, around the end of the novel when FL and her family are being accused of kidnapping Lizzy, he had no doubts about FL at all. She didn't say anything, not even a whisper about her not being involved but he immediately knew she would never do this, especially with her wicked family. He did everything to protect her in every way possible and it honestly makes me a bit sad to see people give it 1-2 stars because of how "horrible" he is.

She ended up marrying OGML which disappointed me a lot. However, I will also say that it is confirmed later on that Cliff and her end up divorcing because he is sick of her showing her true self (hanging out with other men, bullying others, etc...) and she is sent away somewhere. This was a great thing to read about but it still astonished me how Cliff still loved her after all she did to Edith.

I understand the ML had little to no agency early on. I still don't like him, but perhaps we say he's a pass. It still absolutely makes no sense that the FL would love him. She even thinks later that if she hadn't met ML first she would've fallen for the butler. The ML who she met first was awful to her while the butler was always nice or neutral. For both characters it seemed like they liked each other because they were physically attracted to each other versus for their personalities. ML slept with FL early on for seemingly no reason when he was still disgusted by her due to plot.

Like when he was going to 'kill her' like in the OG novel, he chose not to even when she gave up. She didn't ask for help and he did it on his own volition.

According to the story, OG FL was also possessed by the Author of the story and had lived the same life as Lize multiple times. She eventually got bored and chose to have people possess the villain, Edith. She successfully got through 12 lives like this and she enjoyed it very much. She lived a life of killing her readers for self-satisfaction. Then came the 13th (our FL) who acted similarly at the beginning. However, as time went on it became clear that our FL was different from the different Edith's. She convinced everyone of her innocence using logic and soon the ML fell in love. OG FL used her privilege as an author to give rules to prevent FL from becoming 'a good person' as most of the other Edith's tried but the FL broke through the first by attempting to seduce ML. Contrary to OG FL's expectations, FL succeeded and they slept together. The next rule was to reject the ML 10 times and the FL succeeded since she thought ML was testing her. The last rule was to die as a villainess, but there was an exception and that was accepting her death. Time skip to before FL was going to be executed, she accepted her death but ML didn't want to kill her so she broke all the characters free from OG FL's control (she had an extra privilege to control characters with importance but the control weakened every time FL broke a rule) and then she spent time with ML. Soon FL confronted OG FL and said that she won't kill OG FL (I was really annoyed at this point). Instead, FL told her that since this is now a story with an unexpected future she could possibly end up with an even better ending. OG FL and OG ML get married extravagantly and then ML and FL leave to go to their new house. FL improves everything with modern knowledge and also tells ML about her being a transmigrator. He says that he'd try to understand her but he won't unconditionally believe her. Soon, she has to children and they live happily ever after.

Spoilers for OG FL and OG ML: They get married but she keeps wanting attention. So she tries seducing a bunch of people only to have more arguments. She pushes to act extravagantly which causes the Duke to dislike her and the Duchess basically gives up on her. Soon, she attempts to seduce the CP so he falls for her like in the OG story. Fails miserably and she gets scolded by Duke. And then, she tries to find the lost relative of the Emperor to gain favour. To do this, she goes to the s*ave auction where he was before but she only found a lookalike. She takes the lookalike and teaches him how to be a noble so she can fool the Marquis house (said relative was the Marquis' child) this also fails since his birth mark changed to a different area and she was imprisoned. Also, if you're asking why OG ML didn't divorce her, he made a contract. And it basically stopped him from leaving her optionally. Anyways, FL turns out to have found the child but she didn't know. When she visited the Duke's house she brought him and he was found. OG FL was allowed to survive but was sent to a monastery where her marriage was annulled. Then it goes to ML, FL and OG ML talking, he opened up about unconditionally loving her for some reason and I think he said he fell out of love as soon as they got married. But anyways, it ends up with FL telling him to get it together and find someone who he mutually loves. Timeskip to when FL and ML are going to the capital again, OG ML finds someone who he loves like a normal person and they're happy together. Story ends with FL thinking that it was really a common possession.

Dont get attatched to the original heroine, tho in the first parts the MC will also like her. Shes a b*tch, end in end.
