Siwon and Kyuhyun have been best friends since they were born, they liked each other, but never expressed their feelings. It was comfortable like that.

Siwon was 17 years old and a senior in highschool while Kyuhyun was 16, a junior. They both attended the same school, but with the new school year beginning, new students will come to school. There is a certain Shim Changmin around, a 16 years old tall and handsome boy. Kyuhyun only has eyes for Siwon but....what happens when Changmin and him get their lives tangled?
