I skimmed a bit further and I don't have the heart to continue. It's the kind of world that revolves around the heroine - all significant characters either like her or they dislike her, she's the most pitiful, and the ones that dislike her/she dislikes are terrible people with terrible personalities who go through humiliation. Maybe it will progress, but I hate that beginning. I don't even love this heroine, the default setting for most is to care for the protagonists even if they're the originals and she's the new heroine of this story, so those first few chapters aren't fun for me.
This only ever happens in Japanese manga for some reason. There's so many stories now about a villainess being rebirthed but I really would like to read one where they're reborn after they've done all the bad stuff and they head towards redemption. But these stories turn the 'villainess' into the cliche gentle and loving perfect heroine, the world revolves around her and she's just misunderstood. The OG ml is turned into an idiot that just didn't see how great she was, and the OG heroine, if it's an otome game/novel, is someone who fell into the world and got too greedy and confident.
I've read five stories with this premise and they all go the same route. The girl also falls way too quickly for the new Ml when she supposedly loved the guy she was engaged to for years before the villainess's story ends.
The story isn't for me. It's like falling into the world of Harry Potter and finding out Harry, Ron and Hermoine were actually terrible villains and Voldermort and Draco Malfoy were misunderstood saints. The comparison is a bit too much but it's just to give some context. It's why I can't love stories with this premise.
Just a few chapters in and I already don't like this story. I read another story that did the same thing "Character goes into an otome game as the villain, but the villain isn't really a villain and the original protagonists become villains" it's that kind of premise. Can't there be one where the person realizes they were a villain and make up for what they did, fall in love along the way, and not turn the OG protagonists into villains? It feels like I'll lose all confidence in protagonists for normal stories once I stop reading isekais.
