[Quick transmigration, System, never lets a slight go unanswered, training dogs, chastity is a man's best dowry. PS: My personal preferences are loyal dogs, possessiveness, and male submissives. If that's not your thing, please don't attack me.]
After Ji Yue died, she was suddenly bound to a System. And not just any System, but one for tragic romance novels.
The System wanted her to become a stupid, kind heroine who would give everything for love. It also demanded she follow the plot, including but not limited to saving the male lead, acting as a substitute, serving as a stepping stone, being misunderstood, and getting caught up in the brainless “she runs, he chases, she can't escape even with wings” storyline. In the end, she had to suffer both physical and emotional torment before reaching a perfect happy ending.
Ji Yue laughed. She couldn't play the tragic heroine, but she was very good at playing the villain.
So she struck first, took on the male lead, got revenge on the female rivals, beat up the protagonists, and still made time to train the dogs.
She was the heroine, after all. Of course she was the one who got to torment everyone else!
So,
In the first world, when she saw the male lead, who had been set up and thrown into the sea, she didn't hesitate to shove him right back in.
Want to cheat on her? Not only was there no door, there wasn't even a window!
In the second world, she was a little fool offered up as a sacrifice to bring good fortune through marriage. Sorry, but even a little fool can make your whole family fall apart!
And the male lead?
Like she said, she's the heroine. The one she chooses is the male lead.
