Everscince you were a kid you and kenji never got along like never ever got along...long story short kenji is your step brother...your mom remarried and they had a kid, kenji...you were 4 months older than him and growing up together was tough

He annoyed you all the time and he didn't regard you as his sister at all...he also got jealous when u got all the attention..even tho the attention you were given was equal he still got jealous

Time skip

Yall grew up...you moved out of your old home...intact you moved to another city and forgot about your step bro mom and step dad

You were out with your boyfriend shopping...you were in the changing room trying out a new dress you liked..you were in your undergarments then suddenly you felt a hand round your waist...it was a strong grip...then u saw a familiar tattoo on the arm

It was kenji
