It was in the middle of summer. While the adults were on their way to work, the children from the age af six years to eighteen years old were at school.
In Seoul South Korea, there were a lot of schools. But something in the air was different for two young boys at the age of six. In the classroom of "Starbright Elementary School," something in the air was different for two young boys at the age of six. Their rivalry began when they were in the first grade. Always competing against each other. If it was tests or simply answering the teachers' questions, it was always those two who glared at each other.
It was if it was a contant that seemed as natural as breathing. Even as they grew older, their childish games of youth transformed into battles of egos, each of them determined to prove they were better than the other in every way.
Jihoon and Seungmin were completely different from each other. Their personalities were as different as day and night. Jihoon was warm, friendly, kind, loyal, and honest. Seungmin was sarcastic, cold, rude, playboy/bad boy.
As their last year in high school began, the boys are now eighteen. Would things be any different? Will they finally become to understand each other?
