Changjo has a weird sickness...he's being nervous around person that he loves. His crush is his classmate, Chunji. And as he know, Chunji also love him too... Everyday Chunji would gave him a sweet present...sometimes he got chocolate bars, lollipop, candy and chocolate cake that made by Chunji himself... Changjo understand that Chunji put all his sincerely to make all of that for him, but everytime Chunji came closely to him, he unconciuos hurting him...he sometimes beat, pushed, or slapped Chunji...so that's why he keep avoiding Chunji, but Chunji  never give up as he tried to be nice with Changjo...
