Five years ago, designer Lin Wan was set up and betrayed by her best friend, leading to an unexpected encounter with Gu Xiuyuan, the CEO of Gu Group, and a pregnancy with twins—a boy and a girl. Pressured by her own family, who favored sons over daughters, she resolutely cut ties with them and went abroad to give birth alone. Five years later, Lin Wan returns home as a top designer and joins Gu Group, only to discover that the CEO is the very man she met years ago. Desperate to keep her children's secret hidden, she handles workplace challenges with composure, including the deliberate harassment of her colleague Bai Xinran. Gu Xiuyuan gradually falls for Lin Wan, and with the adorable little girl secretly playing matchmaker, he discovers the truth. He transforms into a devoted father and does everything he can to win Lin Wan back. Eventually, Lin Wan reunites with her long-lost biological parents, the Xiao family, and is moved by Gu Xiuyuan's sincere love. At last, the whole family is reunited.
