Shen Lan, the daughter of the Shen family, had her parents killed when she was seven years old and her brother disappeared. She was fostered in the home of her fiancé Lu Yunfan since she was a child. She suffered a lot in living in the care of others, and even deliberately concealed her beauty by pretending to be ugly in order to prevent Mother Lu from giving her away to others. Because she relied on the Lu family to help find the murderer of the massacre and her missing brother, and because she liked Lu Yunfan, Shen Lan had been cautious and devoted to the Lu family for decades. On the day of the engagement party, Shen Lan witnessed Lu Yunfan's affair, and accidentally met Xiao Pei, the leader of the Xiao family. Xiao Pei discovered that the medicinal smell on Shen Lan's body could relieve his headache, so the two formed a conspiracy.
