“I am the one who killed you in our past life. And I am the one who saved you in this life.” A husband who slaughtered his wife's family, and a wife who murdered that husband. Reunited in the modern era with the man who was once her worst enemy, she must now remarry him within a set period. This is the only way to end the punishment of immortality bestowed upon her by a god enraged by Bari's blood-soaked hands. “Kang Hae-an. I can cure your chronic headaches, and I can guarantee the honor and glory of your father for a lifetime.” Hae-an’s parents named him after a calm sea in hopes of a peaceful life, but his world is turned upside down by a single piece of paper handed to him by a woman claiming to be his former wife: a marriage registration form. “If you sign this, I’ll take care of everything. So, let’s get married.” Can Bari succeed in remarrying Hae-an to sever their ill-fated connection from the past?
