The Prince's Contract Bride

He is her senior brother with a mysterious identity. For a joke she made back then, he resolutely gave up the wealth he had obtained, just to be with his sweetheart in this life. He was the object of her crush. Because of a car accident, he lost his memory and became a killer. He had forgotten everything. The only thing he could not forget was the mark on the girl who said she liked him. Many years later, when they met again, face to face, he did not recognize her face at all. He was another prince of Shana Kingdom. He secretly planned conspiracies and launched civil strife just to get everything he deserved. But after meeting that girl, everything changed drastically. He is a member of the royal family, the heir to the throne favored by the Queen, and the prince of Shana Kingdom. He is extremely handsome, gentle with a hint of coldness and indifference, and his beautiful figure makes countless women crazy. Because of the rebellion within the royal family, he was secretly sent to the Alliance for protection, waiting for the opportunity to return to the royal family to rectify the civil strife. She is the number one female bodyguard in Taiwan. She has never failed in any mission she has taken on. For "some reason", she accepted her father's trust and helped him protect the prince from Shana Kingdom. However, she did not expect that this mission would plunge her into an inescapable dispute... This damn philandering young man is actually the prince of Shana Kingdom? Dad, why did you actually give me such a task? His arrogant stallion put on performances that were not suitable for children every day in front of her. If she hadn't been so strong-willed, she would have been in the hospital long ago and became the first bodyguard in history to die from a nosebleed after watching a live-action performance. Is there any mistake? Is this year her birth year? How could one bodyguard mission attract so many people? She is not a fairy, and there is no way to compare one with ten. Why don't these people bring more bodyguards when they go out? Do they really think she has three heads and six arms?
