Jee-eun, a true romantic, is convinced that her love is genuine. One day, she notices a small mole on her boyfriend's face. As the mole grows bigger for unknown reasons, it begins to bother her. Then a new man enters her life, shaking up Jee-eun's entire world.

When a man asks how she can be so sure of love, the woman simply replies that she just felt it. Blind faith, however, is hardly something reliable. In the woman's eyes, who claims to have fallen in love at first sight, the man's mole beside his nose stands out. Just then, an inevitable spoiler appears, and as the fantasy begins, the previous love inevitably ends. This film, a rollercoaster of melodrama, comedy, and fantasy, is both sweet and bitter. Evident attention to detail in the art direction is matched by a parade of music that rises and falls in competition with the ever-changing story. (Lee Yongcheol)
