Ji Sung along with his best friend didn't have any plans for the summer knowing it's the last day of school, until he receives a call from his cousin asking what are his plan and him knowing he doesn't have any. So his cousin suggested to spend time in Korea and hang out with her and her members.

Lee Seung-Hyun is Ji Sung's bestfriend since they were in highschool. he's one of the Heartthrobs in their university along with Ji Sung but difference is Seung-Hyun love the attetion he's getting in their school while Ji Sung doesn't. Seung-Hyun is socialble while Ji Sung is cold hearted. even if Seung-Hyun flirty and socialble to people he meets in school he never really had a real girl friend. cause in school all he does is date them for awhile and finds someone new after a few days or months.
