A Business Proposal, Vol. 1 introduces us to Hari Shin, who has officially hit rock bottom. After being worked to the bone at her office job, meeting her long-time crush's girlfriend, and helping to pay off her family's debt, she's 0 for 3 with work, love, and money.

Luckily, her friend Yeongsuh has a business proposal for her: go on an arranged date in her stead, and Hari will receive a hefty compensation. Things grow complicated, however, when the other party turns out to be her new CEO—and he's got a proposal of his own!
