The male lead is steadfast and persistent, and remains faithful to love in every lifetime. His identity can vary from one life to the next: in the first, he might be a spirited young knight-errant; in the second, an elegant scholar with the world at heart; and in the third, a cold, aloof cultivator. These different backgrounds and identities give him a multifaceted character. The female lead is gentle and kind, meeting and growing close to the male lead in each life. She has a distinctive charm and shares a deep emotional bond with him.
In their first life, the male and female leads meet in the martial world and work together to uphold justice. But conflicts in the martial world and rivalries between sects cause misunderstandings and obstacles, and they ultimately die apart. In their second life, the male lead begins a new journey as a scholar. He reunites with the female lead while traveling to take the imperial examinations or during his studies, but fate plays a cruel trick on them, and they may once again miss each other because of family grudges, differences in social status, or other such factors. In their third life, the male lead devotes himself to the path of cultivation and faces dangers in the cultivation world as he searches for the female lead. This time, they must face powerful enemies together, such as evil forces seeking to destroy their relationship and the many rules and restrictions of the cultivation world. Their repeated meetings, growing closer, and partings unfold in layers, deepening the male lead's obsession with and love for the female lead with every life.
