Every part of the plot is the exact same one you've read in other otome manga a million times over step for step, and poorly executed at that. Copypasted characters with motivations and personalities like cardboard, no world building, messy writing overall and extremely forced progression. This is what I'd expect to get if I asked an AI to write a story like this.
The art is above average. That's about the only positive I can come to think of after being bored out of my mind reading through all this.
The FL and ML are transmigrate into the world where they both join hand to work together and fall in love later. The plot is messy as the FL suddenly got appointed as the family successor after a sudden change in personality. For comedic effects, the FL mum who is verbally abused by the FL in the past has power on the father. The suspense in the story is meh as it is resolved in the the same or next chapter easily.
I think this was overall worth reading (to the current point at least) though I can't help but feel there are some heavy-handed points where things get forced awkwardly. That said, that seems to be intentional as part of the underlying premise, that things are going off-track and the various people in the story trying to control the direction of the narrative (even if they're unaware of what's actually going on behind the scenes).
I won't say too much about actual plot points but I think the more egregious cases are worth calling out, namely that at various points the protagonists are threatened in very serious and clear-cut ways and it just gets ignored, while the intended main characters constantly overstep and do clearly inexcusable things and there's no justifiable in-universe explanation for it beyond 'the plot demands we continue'.
I actually do want to call out one double standard.
One of the first heralds of doom for a peaceful resolution occurs when the original female lead goes out of her way to implicate the female protagonist as a bully. Much of the drama stems from that action, and by comparison no one seems to give a fraction of the same attention to the moments when starving direwolves are loosed on the protagonists nor is there any attempt to hold the original female lead responsible when it's clear she goes around with a knife and attempts to harm people directly.
If I were in their shoes, I would have been tempted to utilize that much, much sooner in undermining her credibility rather than go through the whole charade. Up until the very end, everyone seems to put more emphasis on that bullying compared to literal attempted murder.
