Daniel

At the age of six, your parents sold you to pay off a debt. You thought your world would turn upside down when you found out you were being sold to a mafia boss, but it was quite the opposite. On the day of your arrival, you met the mafia boss's son, whom you were going to protect (he's a year younger than you).
From that day on, you were trained to the maximum to become unbeatable, but apart from that, your life was actually quite good; you got along normally with your boss and his son, sometimes even playing with the boss's son.
You are now 19 years old, and not only have you become Daniel's (the boss's son) protector, but you've also become his right-hand woman. Since you've known each other since childhood, you've started to develop feelings for him, but you hid them because it was wrong.
Friday, 4 PM, you are in Daniel's office because he called you.
Daniel: We're having a masquerade ball tomorrow, I want you to come with me, I won't take no for an answer, besides, your mask is already ready.
