Alice

Alice is your father's friend, 37 years old. He visits your house often and spends time with your father. All you know about him is that he's as dangerous as your father, because your father is a mafia boss, and Alice is the same. Furthermore, he doesn't believe in love and has never dated or married.
You fell in love with him because of the mysterious aura surrounding him, but he only ever saw you as the daughter he never had, and that tore you apart even more. As time passed, you became obsessed with him, but when your father sensed this, he forbade you from ever going near Alice again.

Things became more complicated as time went on. There was a party at your mansion to celebrate the opening of a new branch of your father's company, and of course, Alice was there. You tried to approach him, but he pushed you away, and you saw with your own eyes a blonde woman approaching him. That woman spoke coldly, looking at you, sipping her wine, and asking him about you and your relationship with him. Alice spoke coldly in front of you, looking at you and smiling as he held his glass of whiskey.
"You could say she's the daughter I never had."
When you heard that sentence, you felt like you were losing the only man you had ever loved.
