Shin Ha Ri reluctantly agrees, planning to ruin the date so the man will reject her. However, she’s stunned when her date turns out to be Kang Tae Moo, the CEO of her company.

Kang Tae Moo, a workaholic tired of his grandfather arranging blind dates, has decided to marry the next woman he meets just to focus on work. Unknowingly, that woman is Shin Ha Ri, pretending to be someone else.
