A deal is made between a spy and a serial killer. The deal was simple. As long as they cooperate with each other find the person that they are after, the agent may finish his mission by taking V.D.'s life at the end of the deal. It's very simple. So what kind of wrong turns does this "very simple deal" take?

Heizou hated liars. Maybe it's because of his past friend. Maybe he couldn't bear the thought of him, of how he deceived him, how he himself then left him for this lie until the day of his death. Either way, he still hated liars. He knew that he had reminded Kazuha this many times, to make him promise again and again that he has never lied to him and never will. But he still did. . . . You promised me that you would stay. Lie to me, lie to me that you're okay. *** Five times Kazuha spoke the truth. And one time he lied. A 5+1 things Heikazu/Kazuhei fic.
