Five minutes before the wedding vows, Xu Zhiwu received an anonymous video: his fiancé Zhou Yi signed the old port demolition agreement, and the lighthouse left by his father was also included.
She took off her wedding ring in public and rushed back to Wugang in the rain, only to meet Gu Chaosheng, who was in charge of the renovation project.
One is suspected of being an accomplice in the demolition of the port, and the other is hiding secrets related to the shipwreck. In order to guard the lighthouse and find out the truth about his father's death twelve years ago, Xu Zhiwu and Gu Chaosheng went from tit-for-tat to walking side by side. But when the truth emerged, she discovered that the hardest thing to tear down was never the old port, but the lies and regrets in people's hearts.
