Fate ruled Neji Hyuuga's existence in every way. What Neji found so amazing about Tenten was the fact that fate held no reign over her at all. The weapons mistress held no belief in fate or luck, they were beneath her. If fate had apparently decreed something that Tenten did not accept, she flat out refused to bend to its will. It was as if fate was a tie that bound people to its every whim and Tenten was a knife that would destroy those bindings. That's what drew him to her; Neji knew the only possible way for him to fight fate was with Tenten beside him.
With the knowledge that no matter what happened, Tenten would always stand by his side, Neji didn't hesitate to stand against his uncle when Hiashi informed him of his fate to marry for the good of the clan. He looked his uncle in the face unflinchingly and told him he refused to be the clan's pawn. Neji stood fast through Hiashi's angry retorts and when he had finished Neji left the Hyuuga estate with the few things he could call his, leaving his family name behind. It was a small price to pay to be free from the chains of fate.
As he knocked on Tenten's door that day he wondered what fate had done to make Tenten leave behind her name.
A/N: I have always wondered why Tenten doesn't have a last name.
