Xu Yingluoxia accidentally discovers that she is the reincarnation of her sister Caiyun, and her sister has an ongoing feud with Qiu Changtian, the lord of the demon world. It may be a coincidence, but Luoxia falls in love in this life just to repay her debt from the previous life. Qiu Changtian was originally an imperial guard in the fairy world. He hated the fairy world because of his dissatisfaction with the rules of the fairy world and Caiyun's unexpected death. After his betrayal, he joined the demon world and even joined forces to fight against the immortals, just to subvert the order of the three realms. Changtian slowly found his lost memories while getting along with Luoxia, but it was too late...
Intention: Cherish the person you have now and don't expect the next life.
