There's a few things that seems so wrong here.
It's nice that we got an og FL who's truly nice as she's written and doesn't give a damn about og ML until he started courting her right.
However, can't they do their thing on their own?
"You're her friend, you're my... *Blushes*" lol that's bull. He can give a gag order to anyone who he ordered to deliver his letter, doesn't have to be Nia, the first 2 might be fine, but if she continues to be cupid, they're going to take all the time in her life.
There's been so many of these love bridge trope crumbling in the middle in later part of the novels that they're just meh right now. Still FL should stop that thing. Good thing she's getting jealous now, hope she starts chasing after her interests.
Also, am I the only one expecting the cliche CP will fall in love with Nia? Lol.

The pacing is so quick it's confusing. There's not a lot of build up either, but I stayed for the interaction of the leads. Also her in laws circumstances were similar to 'I thought it was a common isekai story.'

Novel wise, so the novel that mc read in the past was the around the same premise of I thought it was a common isekai story where ogfl was taken into the care of the Duke’s family and the two sons of the duchy fell in love with her as they were all childhood friends. The oldest ends up marrying ogfl while the youngest marries our current fl who in the novel was the villain. The second son not caring about the his wife and only cares about ogfl, which in turn caused her act out. In the end the second son gets rid of her. That all the same. But only difference is this one doesn’t follow the novel that the fl read in her past life or have an author influenced that forces it to follow the novel. Neither of ogmls like the ogfl and our fl isn’t a villainess.

None of these AU yaoi/shonen ai were even close to reality. They happened in the AU where norms were totally different, so what's with their judgement? (⌒▽⌒)
If you can't distinguish fiction from reality best not read any.
Also, we all have different morals and values and there are elements in the stories that we may strongly disagree with, but most people come here for the story. I've been a fan of the genre for a long time and I noticed that as time goes by the storytelling evolved and authors are putting more human actions, decisions, and emotions in the characters, that includes both the good and the bad side. Thus, we see the themes that are morally unacceptable IRL being written out, which the characters will have to overcome.
If you can't keep up with the dynamics of POVs, storytelling, and themes, turn around, keep going and look up some fairytale. (=・ω・=)
Dang Dona and that Gal's delulu is all time high
