In a place where there is no ugliness, Han Jae-i, who calls herself ugly, is a bundle of appearance complexes. Although born from the same womb, she resents her looks that are different from her sister's and trudges to school today as well. Before the morning assembly starts, amidst the noisy chatter of the children, Jae-i lifts her head from the desk where she was slumped over and sees a girl so beautiful that her eyes widen. It was the goddess, Bae Yu-young, who transferred from Seoul. Perhaps because she looks as cold as her pretty appearance, the simple-minded classmates are intimidated by Yu-young's aura and no one dares to speak to her. Then comes gym class. Jae-i and Yu-young are divided into opposing teams for a game of dodgeball. And the dodgeball that Yu-young throws with all her might hits Jae-i right on the forehead. When she comes to her senses, she finds herself in the nurse's office, and through this funny incident, Jae-i and Yu-young become inseparable best friends. As the two enjoy their school life together every day, they suddenly feel confusion over feelings that are not just friendship. Soon, they realize that the feelings they have for each other are not one-sided, and they awkwardly begin a romance. However, their sweet romance is short-lived as Yu-young is set to transfer back to Seoul. Although they are physically apart, when Yu-young suggests that they attend the same university, Jae-i lashes out with harsh words, and they part ways emptily. After Yu-young leaves, Jae-i realizes the depth of her feelings and rushes to Yu-young's house, but she returns home in tears to an empty house that has already been vacated. And with an unexpected fall, she begins to live a spectacular second life.
