Overworked corporate drone Lena dies from burnout and transmigrates into a trashy novel as the cannon-fodder side character Sienna. The original heroine would cling to the villain and end up dead on the streets, yet she holds the full plotline and knows bankrupt CEO Dorian will one day become the richest man. On the day of asset liquidation, she tears up the divorce papers in public and sells all her valuables to bet on a promising stock, standing by Dorian through crippling debt with an investor’s mindset. She fends off her scheming younger sister, a rival heiress and mastermind Julian, evading the story’s destined death flag while growing genuine affection amid shared hardships. In the end, they gather evidence together and expose Julian’s corporate crimes at an industry summit to clear their names. Sienna confesses her transmigration secret; Dorian long sensed how extraordinary she is. Letting go of all calculations, they fall for each other unconditionally and break free from the fixed storyline to start a brand-new life together.
