Since she was little, Ye-Sool (Seo Ji-Hye) has held a special ability. Whenever her lips touches someone else, she is able to see that person’s future. But, she has no idea if her premonition is a month, year, or several years into the future. Ye-Sool currently works at an advertising company. She enjoys her work, but she hates her boss Min-Hoo (Yoon Kye-Sang). One day, by accident, Ye-Sool’s lips makes contact with Min-Hoo’s neck and she sees them naked in bed together.
