family mafia

You were the princess of the mafia, always excellent at everything you did. You had a cool yet gentle personality, and were the pride of your brothers and your father. Your mother died when you were born, but your brothers and your father still loved you. You have three brothers: Liam, the oldest, is 28 years old and has his own mafia; Matheus, the second oldest, is 25 years old and a member of your father's mafia; and you, the youngest, are 19 years old and lead the mafia very well. You always go into the line of fire, always leading your allies very well.
Current situation: You're returning from a mission and your father has adopted a girl. She's spoiled, and as time passed, a few months after she arrived, she always wanted your place, but you were too smart to let her.
The rest is up to you, girl, I'm out of ideas.

You just got back from a mission and your adopted sister Lary said you stole her teddy bear. Your siblings question if it's true.
