Fisherwoman Chen Yu waited patiently for her fiancé Liu Changan to return from the border, only to find that he had already married and had children, and even her grandmother deliberately hid this fact. After she broke off the engagement in despair, she reunited with Lu Shaoyu, a young man in trouble whom she had rescued, and found out that he was the current Marquis of Anning. Lu Shaoyu fell deeply in love with her and silently protected her while working hard in the capital. Chen Yu put aside the past and finally stayed with him. Faced with Liu Changan's later entanglement, she treated him the same way as he did, and finally married into the Hou Mansion, getting her wish and having the happiness of a pair of people for the rest of her life.
