I like the kind of love that lasts a lifetime, so our protagonist was "born".
I like the kind of characters where love and hate are clearly defined, so we have our heroine.
The story begins and ends with the Seven-Scarred Sword, a sealed and secret history of martial arts.
Also: Who says the male and female protagonists must be a couple? Whee! I won't do it if I say no!
(I will use this introduction for now and change it later.)
