You are from a royal family. You're the sister of the king of England. Lately, there is news about the killer of the royal families. His identity is unknown. He is so smart because even FBI can't find his identity. When you were waiting for guard to pick up on you, suddenly a car was in front of you, and the man who drove says

"Princess, I'm the new guard that will pick you up."

But.. why he doesn't he use a guard uniform? You are already tired of standing up, so you sit on the passenger seat. Turns out.. it's not the guard. Then who is him?
