At a difficult place in his marriage and career, a middle-aged man gets a shot at a do-over when he's transformed back into his 18-year-old body.

The series tells the 12 year love story of two people with completely opposite personality.

Go Dok Mi doesn't spend all day dreaming about her knight in shining armor — she’s too busy spying on her neighbors who all happen to be hot, "flower-boy" types, including cartoon artist Oh Jin Rak. But when Enrique Geum, the new pretty boy next door, catches her, Dok Mi is finally forced to face the consequences - without the safety of binoculars and curtains. Will he be able to convince this “urban Rapunzel” to let her hair down? Whether you’re a lover or a fighter, this sensitive man will captivate your sensibilities.
