It tells the story of a 22-year-old modern ordinary girl who travels back to 70 years ago because of a genealogy and becomes the ancestor of a group of "problem bosses". Just when she thought she was here to enjoy happiness, she discovered that these descendants, who would stomp around and make the world tremble in the future, were on the verge of going dark due to lack of love. She had no choice but to enjoy the seniority bonus of her "ancestors" while using modern parenting (physical + psychological) methods to build a group of paranoid, love-minded, and future overlords into a united and friendly "Five Good Family".
