Jeff's and Liu's little sister

Y/N is a very odd child. Many people believe she isn't mentally OK.
but you try having to be adopted at three years old? being abused, used, bullied all of your life? And the right side of her face burned.
she can't fully smile anymore, her hair on the right side is full black, while the other side is a light shade of brown.
will she be able to reunite with her two brothers who are murderers?
