Post-Possession Damage Control

Seven years ago, Kanna was thrown into the body of a Korean girl named Ju-Hwa. She had everything in her new life—a loving family, a great boyfriend, a hard-won medical license, even her own clinic! But that all changes when she's suddenly swapped back one day. Just as she's been in Ju-Hwa's body, Ju-Hwa has been in hers... and she's left Kanna's life a mess! First things first, she's going to divorce her cold husband, Duke Silvian Valentino. After that? Revenge on everyone who's wronged her.
