On the day of his daughter's surgery, Lu Chuan, a resident son-in-law who had endured for two years, decided to change his way of living—from then on, the favors that should be returned would be returned, and the accounts that should be settled would not let a single one escape. For his daughter, he had once bowed his head, tolerated, and even been treated by everyone as a useless doormat; but no one knew that this seemingly penniless man harbored behind him an identity sufficient to change everything. When he finally stopped backing down, the people who once looked down on him, bullied him, and betrayed him would also pay the price one by one. Meanwhile, his marriage with Su Qing, which was on the verge of ending, was also heading toward an unknown direction because of this belated change.
