Yeah, it's a task to basically cuckhold your husband, but than you get jealous when you see him with other woman??? At the very end she says to the OG FL that she shouldn't rely on men to have a living, despite acknowledging that that's the only way a woman could do so in these times (yeah, woohoo lets totally forget about the side characters she made very rich thus proving her point rather useless) and the dumbest thing is that FL also does the same freaking thing??? What happened to being shamelessly in love with money and literally transmigrating and getting instant everything and not earning a single thing yourself Miss girl? The open ending makes literally no sense, if you put all that world building/side plot it NEEDS to have a conclusive ending otherwise it's just a waste of time.

She actually thinks to herself that although she likes the ML, she isn't sure yet if it's just a strong attraction or real love. He is, after all, still a secondary villain who is hurtling himself towards a BE by supporting the ultimate villain (the second prince). If she's going to risk her life and peaceful future, she's only going to do it for real love, not for a crush. A+++

Some people have expressed annoyance at the OG FL's (Fleur) ending not being bad enough, but I disagree. Actually the FL herself acknowledged that Fleur isn't that bad. A little s*upid and petty, but she follows her desires. Again, social climbing isn't a sin or a bad thing. Nor is trying to improve your economic/social situation. We all want that. Yes, Fleur did a lot against our MC, but the original Ophelia started it and did way worse, including physically assaulting Fleur multiple times, hiring people to kidnap and r*pe her, etc. So it's not as if Fleur was scheming against some innocent victim.

Also, considering the fact that everyone forgave the MC for the monsterous things she's done (yes she's a different person, but they don't know that), it would be hypocritical for Fleur not to be afforded the same chance as forgiveness.

(and not too obvious: for example when the FL is in trouble in the midst of monsters, instead of getting s*upid like all the FL novels, she remembers being a black sorceress and saves herself easily, without waiting for the arrival of charming prince)

Sylvester is still clearly against the crown prince, and - if the story follows the course of the novel - to the end would still be killed by the latter, regardless of whether or not Ophelia intrudes on one side or the other. And the FL would follow suit in death, even if she decides to keep their distance from the Prince and Countess Fleur, as the wife of the Villain, unless... well, she's divorced and already far far away at the highlight of the story.
