How the abused female protagonist turns the tide and finds love

I have traveled through time, or... through a book. Before I could even congratulate myself for having the omniscient perspective of a god, I tragically discovered that I had become the villainous female side character in this story. To make it worse, the time period of my arrival is precisely when the female side character's misdeeds have reached their peak and her luck has begun to turn sour, marking the turning point where the original female lead rebounds from her lowest point. Faced with such desperation, it seems I can only devote myself to studying the survival guide for the villainous female side character and seize any opportunity to escape. Unfortunately, I'm also burdened with a bunch of incompetent "pig teammates" - a corrupt and power-hungry father obsessed with political intrigue, a lazy and irresponsible playboy brother who can't seem to do anything right, and the original female side character's antics from the earlier chapters of the novel. At this moment, I am undoubtedly trapped in a dilemma, and even if the author agreed to let me run away, the female lead probably wouldn't. And as for the standard configurations of a romance novel - the domineering and scheming male lead, the gentle and romantic second male lead, and even the third and fourth male leads... they are all under the spell of the Mary Sue-like female lead. As a cannon fodder female side character without a golden finger, in order to survive, I must constantly remind myself not to covet beauty and indulge in foolish fantasies. I must keep in mind the eight-character truth - "There are many handsome men, but none are mine." However, the butterfly effect is never just a scare tactic. The male lead's attitude is gradually becoming ambiguous and unpredictable, and the second male lead, who should have been infatuated with the female lead, has inexplicably begun to target and test me. I don't know if these two men want my affection or my life. The duplicitous male lead, the smiling assassin of the second male lead, and the new, unsuspecting puppy-like third male lead, all of them are harder to figure out than the next. So who should I choose? The collision of values from different worlds ultimately leads to an uncontrollable chain reaction. With the bronze equipment of the villainous female side character in a tormented novel, can I, a diligent and enterprising young woman of the new era, turn the tide against the wind?
