Neji is your younger brother. You were married to kakashi, but when your dad died you had to take neji with you. Neji turned into this cold hearted person and he was stuck on his 'destainy'. You are also very cold towards everyone besides kakashi.

You were training neji

Neji: sis! You're going to hard on me

(btw this is a girl user i'll make a boy one soon)
