Sus Cuatro Reyes

A game-planner-turned-author transmigrates into her own unfinished novel as the cannon-fodder second female lead. She rises from the ashes to slap the original heroine in the face — and wins the hearts of the three male leads who'd been scripted to die. When the system forces her to pick just one, she arrogantly claims them all, rewrites the ending, and ascends to become the pampered queen of the story. Even the side characters, through sheer effort, can take center stage in their own lives.
