Five years earlier, while Ji Hwan was taking pictures with his camera, two girls, Soo In and Gyung Hee, walked into the frame. Ji Hwan falls in love with Soo In at first sight. He then musters up enough courage to confess his love to her, but she refuses him very politely. Even so, Ji Hwan doesn't give up and tells them that he wants to be friends the next time they meet. Ever since then, the three of them have started a wonderful friendship. They spend time with each other always and consider it the most precious moment of their lives. But they become confused between love and friendship and, finally, Gyung Hee and Soo In leave him without a trace.
