Lee Chanhee and Lee Byunghun were childhood friends into their pre-teen years. They were almost inseparable but when they were both 12 years old Byunghun's family moved to America. The two young boys promised to keep in touch with each other but were unsuccessful. Of course, two 12 year old boys wouldn't have all the means to stay in touch.

After 6 years apart, Chanhee, known as Chunji by his current friends, has a pretty good life. The kingka of the highschool along with his best friend and room mate, Niel, Chunji is good-looking, smart, liked by everyone and he knows it. He goes along living his seemingly perfect lifestyle of school and socialism. In his 18 year old self, Chunji shows no signs of his 12 year old past who would cry every morning once remembering his best friend was not going to meet him at the school gate. He has seemingly moved on, lived life and lost innocence.

A real change from the cute little boy Byunghun remembered and began to fall for.
