Lee Ji Eun was the second lead of her own story, always hiding behind the audacity of her best friend. Nobody remembers the second lead's name, only their relation to the main character. Ji Eun was content as "the girl who hangs around Park Jae Mi"... at least until she met Jeon Jungkook. 

Jungkook was a main lead in every aspect of life. He could draw everyone's attention simply by breathing whereas Ji Eun could scream until her lungs bleed and no one would look her way. They soon come to find that you can't have shadows without light as beauty hides behind one's imperfections.
