Lin Yueming received six hundred thousand yuan for studying abroad left by her mother, but was calculated step by step by her boyfriend Jiang Lin under the name of "engagement"—faking illness, stealing cards, cyberbullying, staging traffic accidents, setting up sieges. From trust to sobriety, she secretly locked the trust account, called the police to fight back, exposed the truth publicly at a family dinner, and finally successfully went abroad for advanced studies. Years later, she was calm and confident at an industry summit, while Jiang Lin had become a cleaner. The story conveys the belief that "living for oneself is the best choice"—true growth is bravely walking towards one's own future.
