The First Move
The trick was not to make the first move.
The one who moved first took the blame if it didn't work out. The other was just "reacting" to their feelings and weren't found as guilty. The second move was the safest.
The problem with Kakashi and Kurenai was that both knew this trick.
He wanted her to be sure. She doubted she could be. She was stubborn. He was patient.
One day he suddenly kissed her, not saying why, but immediately she understood.
The trick was to not be left with the second move, wishing you had made the first.
