Ten years ago, Dabi Song endured the blind date from hell. Her date, Jeongheon Han, was a handsome but socially inept student who bored her with thesis talk and abandoned her in a movie theater during a horror film. Dabi thought she would never have to see him again, but destiny had a cruel sense of humor. Now, they are colleagues at the same company, where Dabi is a competent assistant manager and Jeongheon remains as handsome—and as hopelessly awkward—as ever.
The workplace dynamic shifts dramatically during a business trip when a luggage mishap leads to Jeongheon discovering Dabi's personal sex toy. Terrified that her secret will spread through the office, Dabi is cornered when Jeongheon proposes an unexpected deal. He doesn't want to blackmail her; instead, he desperately needs her help. Claiming he wants to win the heart of a specific woman, he begs Dabi to train him in the art of dating and social interaction.
As their secret coaching sessions begin, Dabi finds herself guiding the man she once despised into becoming the perfect partner. However, as Jeongheon improves and reveals a more charming side, the boundaries of their arrangement start to waver. Don't xxxx Where You Work is a mature romantic comedy that explores whether first impressions can be wrong and if romance can truly blossom amidst awkward secrets and office politics.
