Rural single father Zhang Guohua raised a son and a daughter alone after his wife passed away. To scrape together one hundred thousand yuan for his son Zhang Cheng's betrothal gift, he worked desperately hard and was diagnosed with middle-to-late-stage lung cancer. Instigated by his utilitarian girlfriend Lin Meixin, Zhang Cheng resented his father for not returning for three years; his daughter Zhang Junlan suffered an unhappy marriage with a mama's boy, yet still attentively cared for her father. Zhang Guohua concealed his illness just hoping to see his son once, but was repeatedly blocked. After Zhang Junlan tearfully revealed the truth, Zhang Cheng ignored divorce and forced marriage to rush home overnight, feeling overwhelmed with remorse upon seeing the betrothal money his father had hidden, making up for his shortcomings in the final moments.
