After leaving the country for five years, Yongsun and Byulie are back in Korea. But the fear still remains as they may have to face things happened in the past, people part of their past. Both love and hate. As they face each other will they be able to overcome problems? Can they undo the knot or let them get entangled forever... She's still as pretty, thought Yongsun. Maybe she still has a crush on the girl from her school. Maybe Wheein never thought of her that way. Maybe she should giveup. But how....she's been trying to do that for the last 5 years. Unnie still looks as baby as she was. Does she still have those dolphin laughs? She was so cute. I wish I could see that smile everyday. But I am Wheein. I am nothing compared to Joohyun Unnie. Yes...Jung Wheein die alone. . . . . "Oh, Byulie Unnie!" "Hello, Hyejin" "How have you been? It's been a long time. Five years I guess" "5 years, 2 months and 7 days" "Ahh you remember tha..." "5 years, 2 months and 7 days of hating you, Hyejin-ah. How can I forget that...."
