I agree! The closest ones I can think of are "When the Villainess Loves" but while she doesn't go for the original ML, she doesn't care about the original FL at all.
Another one that she doesnt care about the original is "I picked up the second male lead after the ending" but like the title says it's after the heroine came and took the ML.
Hoping other people have some recommendations because it's really hard to find a story where they don't spend the entire series obsessing about the original heroine.
Im not sure if these are exactly what you’re looking for cause in some of these the mc is aware of the Original fl, but not in a romantically way.
Hope this helpsヾ(❀╹◡╹)ﾉ~

I’m tired of these female leads doing so much for an inefficient plan. If she doesn’t want to end up on the destruction route with the male lead, then... just... prevent it. It’s really that simple. He already listens to her like a puppy so all she needs to put in is the elbow grease. And imo the whole “weh weh the heroine will come” sounds like a shoehorned idea by the author and female lead just to make a BS excuse to not use their brain. The story of a female lead trying to prevent the male lead’s downfall after finding out how cute he is sounds much better than this mess. The Evil Lady’s Hero does it better anyways.
Off topic, does anyone have a recommendation of these isekai stories where the female lead doesn’t give a shit about the heroine and happily steals the male lead on purpose? Cause I’m tired of these faux good girls, Virgin Mary wannabes “UwU you wouldn’t be happy with me you belong with the heroine”, braindead lookin ass female leads in the spotlight.
