Through a twist of fate, the heroine's soul transmigrates into the body of a demon princess. The princess was assassinated by members of the Immortal Clan, and her soul was devoured completely, leaving her no chance of reincarnation. In the human world, Zhou Yu was the same age as the heroine, and they were born on the same day, month, and year. By an even greater coincidence, they also died on the same day. After Zhou Yu died, her soul transmigrated into the princess's body, though she doesn't know it. She still wants to return to the human world, and so a new story begins. Let's look forward to it~
