Shuichi Saihara, a young high school boy, transfers to a new school where he meets Kokichi Ouma, a smart, quiet kid who often just gives a cold shoulder to anyone he doesn't care about. Shuichi can't help but feel attracted to this small boy, unlocking a new... scarier... side of him he didn't even know existed. It seems like everything possible goes wrong, but in just the right way. What will happen if Shuichi's emotions get out of control? What secrets about his classmates will be revealed? And, of course one cannot help but ask, what will the casualties of all of these emotions cause? Who will have to pay the price?
