When they reunited ten years later, he was already the leader of the business empire, while she was just an orphan struggling to survive. The appearance of Gu Chenzhou revealed the dust-laden truth: the separation between them was not accidental, but a carefully planned conspiracy. As secrets from the past gradually surfaced, Lin Wan discovered that she was not only Gu Chenzhou's lost love, but also a key chess piece coveted by his business rivals. In the intertwining of love and hate, the two were forced to be involved in a business war that spanned ten years.
