Maybe it was her fault, but then again, perhaps it was the other. Whatever the reason, they were no longer together. They lasted for three years before finally calling it "quits". It wasn't about a fight. No one cheated. They just drifted apart.

Yoona and Jessica dated back in university. After college, Jessica chased her dream of becoming a singer, and now a rising superstar in South Korea. Yoona, wanting to excel in the corporate world, is now an executive in a company.

A year after their break-up, Yoona and Jessica found themselves in the same resort in Jeju. Meeting up accidentally, will they try to mend the drifted memories?
