Bride on fire

At her wedding dress fitting in her mother's boutique, Clara discovers that her fiancé is cheating on her with her stepsister. The traitors lock her in a storage room and set it on fire, leaving her to die in the flames. She's rescued by a humble repairman, to whom she desperately offers a fake marriage in order to secure her inheritance. What she doesn't know is that her savior in dusty boots is a hidden billionaire — a man capable of burning her enemies' empires to the ground.
