Ivy, a world-renowned pop diva, is attacked by a crazed fan and wakes up to find herself transmigrated into the body of an overweight, indebted, and disgraced married woman. The original Ivy was not only infatuated with her lover and squandering her husband's money, but also looked down on her husband, Ethan, a down-on-his-luck firefighter with a hearing aid. Faced with humiliation from a rival, betrayal from her husband, and an impending divorce, Ivy decides to completely rewrite her life. Leveraging her musical experience, she starts by singing on the streets, rediscovering her singing talent through weight loss, training, and countless stage challenges, ultimately transforming herself into a celebrated pop diva.
