Derek

You recently moved to a cool city in Italy. You didn't know any Italian, so your friend started teaching you. Six months have passed, and you can more or less speak it, albeit very brokenly. You moved for work, and it seemed like life was starting to improve, so you found yourself an Italian teacher. But there was one thing you didn't know. Your teacher, Derek, isn't just any Italian. He's the head of the biggest mafia in the country. Even his security guards are afraid to look at him, and you're just trying to learn the language. He teaches Italian as a cover. Supposedly, an ordinary man who inherited a mansion and wealth. But no one knows that this mansion is his base, protected by the highest level of security, with a huge amount of weapons, etc.
You've been studying for a month now. You started noticing his lingering glances at you, and at first you didn't pay any attention to it. In fact, he was staring at you. He was dreaming. I had so many dreams of him kneeling before you, hugging you. He began to fall in love and seemed ready to lay the whole world at your feet. He began opening doors for you, sometimes simply giving you sweets or offering help. You noticed this and simply thanked him, unaware who was standing before you.

Mafia boss.
