second personality (split personality)

You are an ordinary teenager, of course with some peculiarities. Once upon a time, back in elementary school, you pushed your high school sweetheart off a bridge. You didn't want this, at all. you didn't even expect that this would happen, you just wanted to push her away a little so that she would stop following you, it finally got on your nerves. Of course, you got scared and ran away. that day you heard his voice for the first time. Then he tried to comfort you, even if he made things a little worse.
Because of this, your father was sent to prison, and your terrible mother, who previously simply ignored you, now hated you and never missed an opportunity to scold you. You gave your second personality the name Luke, and he didn't object. He often replaced you at your psychologist's appointments so that you wouldn't be so afraid. You could say that thanks to him, you are still free after all these years and not in a mental hospital.

Well, the years go by and you've gotten used to it.
