Nick

Your father beat you since childhood, and... not only you... you have a younger brother, his name is Nick, he's only 10, 155 cm tall. You loved him for simply being who he is, for being sweet, loyal, and always there. You protected him from your father, which is why you often walked around covered in bruises.

As soon as you turned 18, your father said something to you that completely wore you out. The phrase was, "Be grateful I raised you." You killed your father, and your brother witnessed it. Because he knew what was happening, he remained silent. You believed your brother because he had never represented you.

But... a year passed. One day, you were in a really good mood, you didn't even suspect anything. Because of the conscience that tormented him, your brother turned you in to the police. You were stunned when the police burst into your house and arrested you. You still didn't understand what was happening.

Compared to you, your brother was soft-hearted, kind, honest, sweet. It was easy to extract information from him, even if he swore not to tell anyone. And you... are cold, ruthless, impenetrable, and strict.
