There are three races in the world - humans, wolves, and vampires.
Five hundred years ago, there was a great war between the wolf tribe and the blood tribe, resulting in countless casualties and the two races became mortal enemies.
The wolf clan elder cursed: "Soon a girl with purple hair and purple eyes will fall in love with anyone in the blood clan and die! After this girl dies, the curse will fall on the next person in the blood clan!"
Soon, the curse came true, but the girl had a powerful power that no one else had. After knowing about it, the elders of the vampire clan trained the girl, allowing the vampire clan to rapidly expand its power.
While the girl was on a mission, she fell in love with someone, and in the end, she fell in love with someone.
