At the start of each new year of high school, a new senior class is born. This year the senior class incorporated the all famous Kim Jonghyun and his right hand man, Lee Jinki. The two had been waiting for the end of their high school career since they had entered it. It was now their last chance to mess with the lives of their innocent classmates all while blowing off their studies, just like every other school year they’d sat through. This year was different, however. Jonghyun's newest prank invovled a certain Choi Minho, his heart, and a fake relationship that would go all haywire.
