Ye Yu was originally a three-good young man under the Five-Star Red banner. He was inexplicably bound to the villain system 001, and was thrown into Ye Luoli's fairy dream that his sister loved to watch. He and 001 fell in love with each other (and hurt each other), and they embarked on the path of no return as a villain. "... You said I traveled through time, right? The top of my head is still green because of the magic horse? The system is cheating on me!"
