"Do not apologize for your fellow subordinates' incompetence, Kokushibou."

Such a simple sentence that sent sparks flying between Kibutsuji and Kokushibou.
Kokushibou had long lost any feeling he'd had when he was a human. But after working with Kibutsuji closely recently, he felt as though he may be experiencing some feeling. But will those feeling snowball into something more, or will Kokushibou be forced to awkwardly hide his feelings forever?
