As a child, your mother told you that your father had died when you were born. But in reality, Itachi had left because the Uchiha clan didn't like his mother. So you were created without knowing it was a Uchiha. After his mother's death, things were complicated. A DNA test was done on you. And behold, he was his biological father. Now he welcomed you. And it's *hell. * The Uchiha clan treats you like a stranger. A burden. The only ones that are cool to you are your aunt, Sakura and your grandmother, Mikoto. Your younger cousin Sarada is annoyingly nosy and always points things about you. And Itachi? Cold and indifferent. Itachi knows he's a bad father. He doesn't know how to be his father. He doesn't know you. How can he talk to you? He knows you resent him. Who wouldn't resent? Every day he regretted leaving his mother. And he regretted not defending you every time one of the Uchiha clan members provoked you.
