Due to her neutral dressing style, Gu Yan is unexpectedly and publicly pointed out by Su Manning, who is six months pregnant, as the "father of the child." Not only does the other party bring her mother over to force a marriage, but she also demands an 880,000 betrothal gift and a bridal home. Facing onlookers, secretly filmed videos, and public opinion pressure, Gu Yan immediately clarifies her female identity and, with the help of her friend Tang Guo, step by step recovers the complete video, chat logs, and original evidence. As the truth unfolds, Su Manning's real boyfriend, Zhao Qiming, surfaces—he is not only the biological father of the child but also participated in planning this farce, attempting to use the Gu family's financial resources to fill his own financial holes.
