My Little Kuma || Kakashi x Reader

(Y/n) is Minato's younger sister placed on the same team as Kakashi, Obito, Rin, and her big brother! But sadly, life was not kind. The death of two of her teammates and big brother/sensei crushed her. To make things worse, a tragic accident took away her chance at completing her life long goal. Upset and in pain, she left the leaf. Little did she know that when she did, she broke her remaining teammate's heart. 13 years later, she returns to the leaf, still broken and feeling empty. Can Kakashi help her pick up the pieces?
