- Description from Novelupdates

Akira Tsukihara was a romance author who despised love. Though she wrote best-selling novels filled with idealistic romance, she harbored nothing but contempt for the genre and the readers who adored it. Love, in her eyes, was a lie—an illusion that blinded people from the true forces of the world: power, betrayal, and ambition. One night, in a fit of frustration, she cursed love itself... and woke up trapped inside one of her own stories.Reborn as Aira, a nameless peasant girl in the Kingdom of Seraphis—a world she had meticulously crafted—Akira quickly realizes that reincarnation isn’t the fantasy dream she had written about. She isn’t a noble, a princess, or a heroine blessed with beauty and power. She is a nobody. A commoner, struggling to survive in the harsh realities of the medieval world she had once designed as a mere backdrop for her grand romances.As Aira, she faces starvation, endless labor, and the crushing weight of insignificance. But Akira was never one to accept fate. If she couldn’t escape this world, she would rewrite the story on her own terms. She would carve her name into history—not as the lovestruck heroine of a cliché romance, but as the mastermind who would bend the world to her will.In a land ruled by noble bloodlines and political schemes, where the romance tropes she once loathed play out before her eyes, Aira sets her sights on one goal: destroying the very ideals of love that had imprisoned her in this wretched world.Even if it means becoming the villain of her own story.

When Su Jiu dies on her eighteenth birthday, she transmigrates into a novel about painful love and becomes an adorable four-year-old child.
