Daisy and Cane were arch-enemies in high school. They fell in love as adults and got married, but a sudden accident on their wedding day left them both with amnesia—their memories reverted back to age eighteen. When Daisy wakes up, she's horrified to find herself married to her nemesis and now a wealthy socialite. Cane is in a coma, but fully conscious. To keep her fortune, Daisy agrees to take care of him—but her clumsiness constantly makes things worse. Cane, already awake, chooses to keep pretending in order to keep her around. Daisy figures out his act and decides to play along, setting traps to force him to "wake up" on his own. Through their push-and-pull, they get to know each other all over again—and Daisy falls in love once more with the man she used to hate the most.
