Zale has awoken before Soren. He couldn't feel his right arm any longer because it had become numb from being used as a pillow.
Zale smiled softly at his peacefully snoring mate. He caressed Soren's face and pecked his brow gently so as not to wake him up.
He was still in a trance in which everything seemed to be a dream. He couldn't believe he had found himself a mate with whom he had made love until dawn and was now sleeping peacefully in his arms. And it all occurred in just one night. In one freaking night.
He was indeed very optimistic and delighted; life was lavishly showering him with good fortune. Although, at the same time, he was terrified and sceptical of the happiness he was experiencing.
It's similar to when you started to have doubts when everything was going well.
