There were 3 bestfriends. Yoon Raeri, Jeon Jungkook and Lee Minah. Jungkook and Minah were a couple leaving Raeri alone. Even though lots of guys had tried to woo Raeri she rejected them all. Becuase her one and only heart is owned by her bestfriend, Jeon Jungkook. 2 years ago, Minah had left Seoul for Paris to pursue her supermodel dream. She promised to return after 2 years. Although Jungkook was sad and depressed, she let Minah did what she wanted. But as the time passes by, Minah was always busy and did not return any of Jungkook nor Raeri's call. Soon after, Raeri became a replacement for Minah.

She knew she can never be as important as Minah to him. She knew she could never take over Minah place in his heart. She knew he would never feel the same back to her. She dare not say anything to him, she dare not even confess, she dare not even look at him into the eyes. She didn't want him to find out, how she feel about him all this while. She want him to be happy, even though she is not the reason why.
