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.
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.'
