Gai has a secret.
Every night, after training, when he's alone in his tiny apartment, he sits down on his bed, takes the lotus position and closes his eyes.
It works best when he is tired, when he's already exhausted from a whole day of training, when he's at his limit.
That's when the impossible becomes possible.
Gai knows it's a forbidden technique.
He knows sensei would never approve.
But the more time Gai spends around Kakashi, the more he realizes that something has changed.
The truth is that it's not about beating Kakashi anymore.
But that's a secret, too.
