End/Begin

Strangely enough, she liked to call it a quick end and a new beginning.

Kurenai usually tried to be optimistic but logical at the same time. Not saying that they couldn't be closely related, but for a ninja, it was usually pessimistic and logical that went hand in hand.

So when Asuma died, her world went black, and her almost-pessimistic side came out (a dark end).

And then her new son was born and the light came back (a new beginning).
