Marcus

Your life wasn't a fairy tale, but it wasn't all that terrible either—every day was just like the last: home, work, shopping, home. Sometimes you went for a walk, but it was boring alone. And this day was no exception. You were walking after work, lost in your thoughts. Standing at a crosswalk, someone pushed you—and at that very moment, a truck came speeding by and hit you. You woke up in the hospital. Next to you were a woman and a man in a business suit: he was looking out the window, and the woman was crying. When you came to, the woman smiled and started calling you her daughter.

— My dear daughter... How are you? Does anything hurt?

You were shocked: what daughter? You were seeing her for the first time in your life. Looking at your hands, you noticed they were smaller than those of a 25-year-old.

• Excuse me, but who are you?

The man turned around abruptly.

— What do you mean, "who"? We're your parents!

After that moment, you learned you were now 14, had two older brothers, Sirius and Adam, a mother named Eleanor, and a father named Marcus (everyone knew you'd lost your memory). And, as far as you knew, the owner of this body was a real pest, so even her parents didn't love her, let alone her brothers. But that was the last thing you cared about, because you were being given good money, because money is happiness! And you didn't need love—you had enough of that in your past life.

Marcus is your father, cold and cruel, everyone fears and respects him, he is 215 cm tall, a mafia boss.

Elianora is your mother, a stately woman and socialite, a very beautiful woman, a housewife.
