Kang Han-seong lived and died as a ruthless underworld legend. Twenty-three years later, he wakes as Kim Si-yoon—the baby daughter of a gifted rapper and composer. With his memories, temper, and frightening competence intact, Si-yoon grows from an unnervingly sharp child into a prodigy who leaves her mark on music, acting, art, games, and everyone around her. A sprawling modern fantasy about family, celebrity life, old loyalties, new bonds, and one very unlikely second chance.
