What's Up Fox? (여우야 뭐하니, also known as Foxy Lady) is a 16-episode South Korean television drama broadcast by MBC in 2006.

Ko Byung Hee is 33 years old, working as a reporter in a third-rate magazine company. She frequently finds it hard to cope with the blandness of her life. What she dreams of is working for a company that she can be proud of and finding a man who can provide warm support when she needs it. In addition, she wants to travel in a camping car (translated RV) with her new love.

A night of binge drinking has her ending up with her best friend's 24-year old brother, Chul Soo. He works as a car mechanic but has adult-sized dreams for the future. Beset on all sides by approbation, they tiptoe around a possible relationship, at least until they realize that true love is just around the corner.

The series looks at the unique romantic relationship of "dating a friend's brother" and "dating my sister's friend" as well as the age gap between lovers.

"Foxy Lady" is written by Kim Do-woo who also penned the wildly popular ''Series/MyLovelySamSoon''. Producer Kwon Suk-jang, who has created such fun-loving dramas for women such as "Lady Next Door" and "Marry Me" is in charge of the production.
