Ji Mingwei wants to know who killed her father years earlier. She is known as the first beauty of Jinghai, and she is with Lu Jinran, the younger brother of the man who heads the Lu family. Lu Jinran wants to travel with the woman he is seeing on the side, so he sends his twin brother Lu Shiqin to take his place beside her. Mingwei finds out what has been done. She keeps that to herself and goes along with the swap, using her position next to Lu Shiqin to look into her father's death and to settle with Lu Jinran. She gets what she was after. When she moves to end the arrangement, Lu Shiqin turns out to have been serious about her.
