On the day of her wedding, Tang Yu'an, the daughter of the Tang family, saw through the conspiracy of her fiancé and second uncle to seize shares through a marriage alliance. Wearing her wedding dress, she fled to the seaside, where she was saved by Gu Nanxing, a beachcomber and ship repairer. To break free from control, she proactively proposed a three-month flash marriage agreement, took over the loss-making bay wedding tourism project, and started her business anew in the fishing village. Little did she know that the "poor husband" looked down upon by others was actually the head of the Gu family. After their identities were revealed, the two separated due to concealment. In the end, Tang Yu'an reclaimed the Tang family with her strength, and when putting on her wedding dress for the second time, she truly chose her own career and love.
