We Are Not Made For Love (A Kakashi Hatake Fanfiction)

They were friends, then rivals, then lovers, then married, then parents...then not.
◊
The Nyoko clan were cursed, hexed by a scorned ancestor- none shall wield the Zodiac Kekkei Genkai and no Kunoichi shall find love with her soulmate. Generations suffered and the clan dwindled without its legendary Zodiac Summoning Technique.
Until the birth of Chihiro Nyoka.
Having gained the Zodiac's respect, the curse is broken only for her and she activates the Kekkei Genkai, causing her jealous siblings to turn rogue. Hoping both curses are broken, she and Kakashi Hatake are married in secret and begin a long life together.
All is well until they find out they're about to be parents. With different opinions on the situation, the two head out on separate missions, both ending with disastrous results that cause them to bitterly separate.
Torn, Chihiro takes a long mission and leaves Konoha, returning years later upon the Hokage's request.
Now having to work close to her estranged husband, while always on the look out for her vengeful sister and evil on the village's horizon, Chihiro is living a life she never wanted.
But with students who love her, a knuckle-headed ninja hellbent on getting the couple back together and the barely-there red string of fate still tying her to Kakashi, she may just have broken both curses after all.
