While applying for a loan, Lin Wan unexpectedly discovers that she has apparently been married without her knowledge. Her unknown "husband," Jiang Hui, has accumulated nearly two million in debt and is trying to make her jointly liable for repayment. Following the clues, she uncovers the truth: her stepfather, Cao Zhenshan, conspired with Jiang Hui to forge marriage documents to pay off his gambling debts, while her mother knew everything and silently approved. Lin Wan calmly gathers evidence, gets the fraudulent marriage registration revoked, and has Jiang Hui's household registration canceled, rendering all his identification documents invalid. She records undeniable proof and reports the crime to the police, ensuring her stepfather is convicted. She decisively cuts ties with her birth family and ultimately purchases her own home, taking complete control of her life.
