60 days. It's like a mantra, a heartbeat inside Nagisa. A constant reminder. 60, 60, 60. Two months. 8 weeks. 1460 hours. 87600 minutes.

It's in his dreams when he falls asleep. A clock, that ticks every minute away. When he wakes up he thinks of it. Every second spent sleeping, walking, eating is a second not saving Koro-Sensei. A second wasted. So he has to keep thinking.

Thinking of this, or thinking of him.

"Gakky!"

"My name is Gakushuu, Nagisa!" he yelled, turning bright red, but the other young boy had already hit him with a hug. He automatically wrapped his arms around Nagisa's waist.

"You can call me Naggi! Gakky and Naggi - a fierce double act!" announced Nagisa. He laughed.

"NO!" he screams, before he can even think. His mother comes running into his room, immediately hugging him, like he did to Gakushuu all those years ago.

"Nagisa! Are you OK? Why did you scream?" she asks him, looking in his eyes and checking for intruders.

"Sorry mum," he says. "I just.. I felt... Never mind." He still isn't comfortable with opening up to his mother, half-afraid she'll go into one of her fits of rage again. It wounds her, he knows, that he won't talk to her, but she keeps it in, keeps her distance, waiting for the day her son will be able to talk to her.

They haven't got a lot of time to reconcile.
