I Do, I Do

Hwang Ji An is a successful shoe designer whose life revolves around her work. She's fiercely protective of her designs, though they are constantly being copied, flooding the market with cheap knock-offs. Park Tae Kang is a young, talented designer, but still regularly rips off Ji An's designs for the easy money. A particularly bad day for the both of them brings them together over drinks, leading to a one-night stand. They swear never to see each other again, but things get complicated when her company hires Tae Kang as a new employee, and Ji An discovers that she's pregnant with his child!
