The heroine learned that her supposedly dead husband didn't die because he encountered a woman he admired at the border, so he faked his death and lived under an assumed identity.
Upon discovering the truth, the heroine was filled with resentment and anguish.
Then she was reborn, returning to the time when she first heard the devastating news of her husband's death. This time, she no longer chose to remain faithful to him but remarried, marrying her husband's good friend.
Since the old lady had only one beloved son, the heroine turned from a daughter-in-law to a daughter of the old lady. To continue the family line, the old lady decided to adopt one of her deceased son's good friends as her son-in-law.
