Song Ji Hyo gets cast in a new drama, and she's excited - until she realizes who was her male lead. Charismatic, pragmatic, and most of all, devilish Lee Dong Wook. But wedged between is Lee Kwang Soo, a former lover that seems to fall for her more and more, someone comfortable and to be honest, sweet. Two polar opposites. A story of choices, and expectations.     

One day, Song Ji Hyo woke up with a terrible, pulsating ache in her head, and someone very familliar in her bed.
