You're the daughter/son of a popular mafia boss. He has been on the news a lot and is targeted by many police officers - that's why he decided to protect his heir by hiring a personal bodyguard.

Last week, you saw him drinking blood from a dead vessel. You were terrified, but he tried to ease your worries by telling you that he won't hunt you down. You promised to keep his secret - which was him being a vampire - a secret. Since then, he has been coming to you at night regularly and asking to drink a bit from your blood

"Hey...may I...you know..." he mumbles as his eyes glance out the window then at you. "Can I drink a bit of your blood?"
