Courier Chen Mo worked tirelessly to support his ex-wife Zhang Lina through graduate school, only to be kicked out with nothing by her money-worshipping family just before her graduation. On the day of the divorce, he encounters the heart-attack-stricken tycoon Su Zhenbang and boldly steps in to save him. To repay the favor and fend off her family's pressure to marry, Su Zhenbang's granddaughter—the icy female CEO Su Qingxue—signs a one-year contract marriage with Chen Mo. When the ex-wife learns of this, she flies into a jealous rage and teams up with the playboy He Jianyuan to relentlessly harass and maliciously frame Chen Mo. No longer holding back, Chen Mo strikes back with precision and skill, making the two reap what they sow. As they spend time together, their fake marriage turns real, and Chen Mo—refusing to rely on the wealthy family's protection—builds his own successful business from the ground up. When the Su family faces a business crisis, he turns the tide and ultimately earns true love and respect, while the villains get the punishment they deserve.
