What if you have someone next to you all your life... Since Kindergarden. Someone who is with you all through elementary and middle school. Who makes you smile on your worst days, when nobody else can. Someone who knows every little thing about you. Who has always been right next to you. Someone who has seen you grow up and change. Who has been your second half. Someone you fell in love with at the beggining of highschool three years ago... What if that someone disappears without any warning and there is no way to get them back? Cat looses Luke. Her everything, her best friend. From one day to the next one, he is gone, and he doesn't come back. At least not the same.
