On the day Shen Wanqing claimed a post-tax jackpot of 146 million, her fiancé of four years, Du Minghao, broke off their engagement and demanded her project deliverables and a 380,000 down payment for their bridal home. She cut ties, resigned, and returned to Qinghe County to care for her maternal grandmother, Wang Guizhi, only to run into a series of schemes including her birthday banquet being usurped, pension funds being embezzled, relatives staging fake donations, and bogus nursing bills. After the jackpot news was exposed, Du Minghao and her relatives fabricated a lottery agreement and an 800,000 IOU to extort money from her. Using evidence, Shen Wanqing fought back step by step, making the greedy pay the price, while also realizing Zhou Cheng'an's sincere feelings and living a grounded, warm life once again.
