194 days.
Niou sits in his bed and gazes out his bedroom window. Bees will work and things will grow off of things that had once grown themselves. And it must happen or it can never happen again.
His head hurts and he knows its possible the treatment is not working. He does not tell Marui, who sits at his side with his laptop, because it would hurt him.
Everyone dies, Niou knows this and accepts this, but he knows that people hurt while they are alive and inevitable death does not make that hurt any less painful.
