The Coldhearted Woman in Tragic Novels [Quick Transmigration]

Blurb:

Bo Fu is the heartless woman in a tragic romance novel.

She's the ex who breaks the protagonist's heart, and then she has to put on a show in front of all these men, pretending she's found true love. The love-struck protagonists get bitten once and stay wary for ten years.

But suddenly, all the scripts go off the rails.

Part 1:

In a struggling young man's story.

The protagonist supports his girlfriend through college, only to be abandoned. His sincere love is cast aside like trash.

Utterly disappointed, he cruelly exposes her true nature, ruining her reputation. The rich young man she's dating also breaks up with her, pained by his own emotional fastidiousness. He can't forget her, but he can't accept that she ever loved someone else.

Who could have guessed that when she later meets her true love, she can be so gentle, as if she'd never been cold to him at all... He'll never understand why. Why? Was he not worthy of her love?

But after Bo Fu enters this world made flesh from words, the man from the countryside devotes himself to her, yet he's gloomy and jealous. He's always suspicious that the other tenants are badmouthing him behind his back and trying to steal her away... After she dumps him, he posts on the campus forum in the tone of a bitter husband, only to be cursed out and doxxed. People uncover that he used the tuition he'd fronted as leverage to make Bo Fu become his girlfriend. He sweetly replies that after they broke up, he became a servant in Bo Fu's house.

As long as I get to see her every day, I'm happy to do anything.

Heh. Whoever marries Bo Fu in the future, I'll keep watching them forever. Heh.

Part 2:

In a rebirth revenge story.

Reborn, the ruthless and decisive true young master is determined never to fall for Bo Fu again, after she treated him cruelly and climbed over him to get ahead.

So he schemes to get his foolish half-brother, the illegitimate son who used to follow Bo Fu around, to marry her. Sure enough, the foolish brother repeats the same mistakes as before, but loves her a hundred times more passionately and beautifully. He becomes the one everyone says she ought to love, and she even starts to waver... while he becomes the most peripheral figure in this drama.

She shouldn't love anyone. She shouldn't... How could this happen? Why?

By the time Bo Fu enters this world, the rebirth wish-fulfillment story has become a cult film. The protagonist from the original timeline hunts the reborn protagonist all over the world and slaughters everyone at the engagement party, where the groom has been switched. He dodges every hand reaching for the wedding ring, clutches it tightly in both hands, and swallows it whole. Mine. Mine. The engagement is mine. The lover is mine. This world that gives my beloved away is false.

And so the world begins restarting endlessly.

Even if our love was doomed from the start, how could you cut out the beautiful things I was meant to experience, right up to their decay? Damn you, future me.
