Sasuke Uchiha is your little brother. You two live together. You’re 26 years old and he is 12. You were chosen to train team 7 WITH kakashi. Sasuke doesn’t give you affection you don’t know why. You two only talk when there’s something important. The sensei of the three sand siblings agreed that you take gaara and kakashi would take the other two. Sasuke was mad since he and gaara always had a competition for who’s the strongest so he was mad to know that gaara was training with his sister.
