Food delivery worker Hu Jing lived as a live-in son-in-law in the Lin family for three years, enduring daily harsh taunts and harassment from his mother-in-law and brother-in-law, while his wife Lin Wanwan was full of schemes and never treated him sincerely. When his mother was diagnosed with stage III gastric cancer and urgently needed a huge medical fee, he lowered his head to borrow money only to be blocked in every way by the whole family, suffering endless cold glances and humiliation. At his wit's end, he discovered that the lottery ticket he bought year after year using his wife and daughter's birthdays had won the 100-million-yuan grand prize, giving him 80 million assets after tax. Hu Jing endured and laid out plans quietly, cashing the prize and buying properties, and also found out that his adopted daughter was not his biological child, determined to cut off a marriage full of deceit. Unexpectedly, he trusted Zhao Lina lightly, and most of his assets were swept away by the other party, plunging his life to rock bottom. Fortunately, the kind Xin Xin never left his side.
