Li Wushuang, daughter of a northern magnate, grew up taking on the identity of her twin brother, Li Weiyi, after he went missing. She diligently learned all kinds of skills from a young age. To find her brother, she studied computer science and used the internet to track down someone in Hangcheng who might be him, based on age and appearance. To make the search easier, she went alone to attend university in Hangcheng.
Lu Hao's father was a diplomat, and Lu Hao had a gift for languages. Growing up surrounded by them, he learned several foreign languages. But he had no desire to follow in his parents' footsteps. Interested in criminal cases, he got into the law school of a prestigious university in the south.
Qi Shan, the son of a southern merchant, fell in love with Wushuang at first sight when he was young. But he resented Wushuang's father. He later moved south with his own father to build their business, and never saw Wushuang again.
The three of them meet again, one by one, in Hangcheng in the south. Their feelings, grudges, and misunderstandings shift as one event after another unfolds.
