Yi-re is a mid-30s publishing house employee. She has a home, a job, and lives happily, but there's just one thing missing. A boyfriend. Her mother sets up blind dates for Yi-re every day, urging her to get married. Exhausted by this, Yi-re decides to take drastic action. "Would you mind being my boyfriend for just one day?" Shaggy hair covering his ears and an unkempt beard. Yi-re's eyes light up as she looks at Sung-woon, dressed like someone anyone would mistake for unemployed. This man has the perfect conditions that Yi-re wants. She wonders if he might refuse. Just then, the man calls out to her. "How should we do this?"
