I’m not entirely sure why this drama is called What’s Up, Fox?, but I think they made a reference to it in one of the episodes.

What’s Up, Fox? is the story of Go Byung Hee, a 33 year-old that lives with her mom and works at an adult magazine, and her love with Park Chul Soo, the younger brother of her best friend and friend of the family. Chul Soo is nine years younger than Byung Hee so that of course causes a big rift in their relationship. But their age difference is nothing compared to the one between Byung Hee’s younger sister, Jun Hee, and the object of her affection. Jun Hee is a model and she meets the extremely rich, extremely irritable fashion importer. He’s 17 years older than her. At first she hated him and she hated that he wanted to be her sponsor. But as we know love can quickly spring from hate. Byung Hee on the other hand has always loved Chul Soo, but as a brother. After Chul Soo’s parents died, Byung Hee’s mother was like a mother to him and his older sister (Byung Hee’s best friend), Seung Hye. Anyway, we know how these dramas go, things come in between them, including themselves but the ride is joyful and hilarious. And the leads are so great to watch. Go Byung Hee being played by the adorable Go Hyun Jung, famous since her appearance in one of the highest rated dramas of all time, Sandglass. And Park Chul Soo is played by the equally adorable Chun Jung Myung, who I adore.
Watch this! It’s not perfect but it’s worth it.
